[+] new feature
[-] bug resolved
[*] bug resolved and functionality improved
[+] Additional administrators on Panel for Linux. Administrators can create additional administrator accounts on Panel for Linux (this was earlier available only on Panel for Windows). Additional administrators are the Administrator level accounts that have virtually all the privileges that the actual server administrator has. The only exceptions are: management of additional administrators and clearing the action log.
[+] Multiple PHP versions. Administrators can install any PHP version on the server in addition to PHP supplied with Panel. After registering this PHP version in Panel, administrators will be able to select it in service plan settings. Customers will be able to select this PHP version for a particular website.
[+] Per-website configuration of the Apache web server. Customers can set a number of Apache settings (MIME types, handlers, access restrictions, and index files) for a certain website. Administrators can also set any Apache directives for a certain website in the customer's Control Panel.
[+] Per-website configuration of the nginx web server. Administrators can set any nginx directives for a certain website in the customer's Control Panel. Customers can switch nginx to the transparent mode for a certain website. In this mode, all content (including the static one) is delivered by Apache, while nginx only passes all the requests and responses. This mode is useful when troubleshooting site issues caused by web server configuration.
[+] Serving static files directly by nginx. Customers can enable nginx to serve static files directly (without passing requests to Apache). This can improve website performance, especially for sites with high loads.
[+] Processing PHP files by nginx. Customers can enable nginx to process PHP files by means of PHP-FPM (without passing requests to Apache). This can improve web apps performance, especially on sites with high loads.
[+] Predefined web server configuration in service plans. Administrators can predefine Apache and nginx web server configuration in service plans. This configuration will be used by default on all websites of customers (plan subscribers).
[*] 301 and 302 HTTP redirects for sites with the forwarding hosting type. Customers can specify the type of the HTTP redirect code to be used for a site with the standard forwarding hosting type.
| Before | Now |
| The 301 redirect is always used. |
Customers can specify which of the redirects to use:
|
[+] Search engine-friendly domain aliases. Customers can set the 301 (search engine-friendly) HTTP redirect for a domain alias. In this case, search engine ranking will not be split between the alias and the original site.
[+] Automatic generation of customers' passwords. Administrators can automatically generate a password when creating a customer. The password will be sent to the customer by email.
[+] Access to the Control Panel for mail users. When creating a mailbox, customers can specify whether Panel should create a corresponding user account.
[+] Improvements in File Manager. File Manager in the Control Panel offers a number of new handy features: Uploading files via drag and drop, uploading of multiple files, file preview, and others.
[+] A database user can access multiple databases. Customers can now create database user accounts. The created accounts can be of two types:
[+] Database server selection for customers. Customers (if allowed) can select any database server registered in Panel for their own or apps' databases, as opposed to using the default database server. Administrators can grant their customers such an ability with the Database server selection permission.
[+] Support for FTP Secure. Panel users can access the server over FTP Secure (FTP-SSL). Administrators can adjust FTP security policy: allow only secure FTP-SSL connections, allow both secure and non-secure connections, or switch off FTP-SSL.
[*] Improved file structure of virtual hosts. The default website file structure (virtual host template) is more clear now.
| Before | Now |
|
|
[*] Improved logging for backup, restore, and transfer operations. The log files of these operations are now stored in a more convenient and clear way.
| Before | Now |
|
Backup PMM/sessions/<timestamp>/ psadump.log Restoration PMM/sessions/<timestamp>/ psadump.log conflicts-resolve.log Transfer PMM/sessions/<timestamp>/ migration.log PMM/logs/ pmmcli.log migration-handler.log migration.log |
Backup PMM/logs/backup-YYYY-MM-DD-HH-mm-ss/ backup.log export.log Restoration PMM/logs/restore-YYYY-MM-DD-HH-mm-ss/ import.log conflicts.log deployer.log Transfer PMM/logs/migration-YYYY-MM-DD-HH-mm-ss/ backup.log import.log conflicts.log deployer.log |
[+] Preliminary check for migration and transfer. Before transferring data from one server to another, Migration & Transfer Manager performs a check for potential transfer problems. This allows administrators to prepare for the migration (transfer) operation: free disk space for temporary files, install required components to a destination server, and so on.
[+] Administrators can forbid customers to change the names of the system users* associated with customers' subscriptions. The permission is located on the Tools & Settings > Server Settings page.
* This user name is used, for example, to log in to Panel through FTP.
[+] Forced upgrades for Testing release tiers. Panel preview builds are now automatically upgraded to the next preview version. Such forced upgrades will be disabled at the end of the preview program.
[+] Panel users can use the apostrophe (') symbol in mailbox names.
[+] Before performing the default backup, Panel checks for free disk space needed to store the file. If there is not enough space, the backup is not started.
[+] Clearing mail queue. Administrators can clean the mail queue using the corresponding button in Tools & Settings > Mail Server Settings > Mail Queue.
[+] Detailed usage statistics. On the Statistics tab inside a subscription, Panel users can view disk space usage in more details: statistics about logs, backups, chroot directories, configurations files, and anonymous FTP directory.
[+] Panel users can use the underscore symbol ('_') in the DNS CNAME records. This symbol is required, for example, to configure DKIM.
[+] Adjustable autoresponder reply frequency. Users can specify how frequently a mail autoresponder should reply to the same email address (on the Mail > email account > Auto-Reply tab).
[+] Skipping a confirmation dialog for operations on Panel objects. Panel users can perform operations on Panel objects skipping the confirmation dialog if they run an operation using the (SHIFT + click) combination. For example, you can remove a number of files in File Manager without confirmation, if you click the Remove button while holding the SHIFT key.
[+] Service plan cloning. Administrators can create the exact copies of service plans (using the Service Plans > Clone Plans button) which is useful when creating a set of similar hosting plans.
[+] Preliminary checks before transfer. Migration & Transfer Manager performs a number of checks on target and destination servers before transferring data. This allows administrators to determine and fix possible transfer issues.
[+] Support for transfer of websites with remote databases. Migration & Transfer Manager allows transferring websites which have databases located on remote servers.
[+] Support for the mixed case in domain names and mailbox names. Panel accepts domain names and mailbox names written in the mixed case.
[+] Improved performance of the backup operation. Server data is backed up much faster due to the support for the multi-threaded gzip compression.
[+] Restricted API RPC access. Administrators can allow communicating with Panel through API RPC calls only from specified IP addresses. The list of allowed addresses is added to the panel.ini configuration file.
[+] Support for OpenSUSE 12.2. Panel can be installed on OpenSUSE 12.2.
[+] Troubleshooting improvements. The special cfgmon utility allows administrators to track changes in critical configuration files. For example, to see the history of changes for /etc/hosts, administrators can run the command /usr/local/psa/admin/bin/cfgmon -s /etc/hosts.
[+] Support for third-party repositories. The Parallels Installer utility provides the support for packages installed from third-party repositories (like Atomic, Remi, Percona, IUS, and so on). For example, if Percona Server from the Percona repository is installed on the server, Panel upgrades will not fail anymore.
[+] Easy disconnection of Customer and Business Manager. Administrators can easily switch off Customer and Business Manager if it was installed by mistake (for example, as a part of the full installation). This can be done in Tools & Settings > Interface Management > Interface Controls Visibility > Disconnect Customer and Business Manager.
[+] Support for SpamAssassin 3.3.2. Panel 11.5 now supports SpamAssassin 3.3.2.
[+] Dynamic changing of notification thresholds of the disk space and traffic usage. Administrators can specify the Notify when disk space usage is reaching and Notify when traffic usage is reaching parameters of service plans in percentage points (%). This allows Panel to dynamically change the notification threshold when additional disk space or traffic are allotted to a subscription.
[+] Suspending of the web hosting service on a site through the API RPC. The site API RPC operator now allows administrators to suspend only the web hosting service on a particular site or alias. The DNS and mail services continue to work on the site.
[+] Improved managing of Panel server from the command line. The new utility plesk lets Panel users connected over SSH easily perform a number of operations on the Panel server: run Panel command-line utilities, manage databases, edit configuration files and so on.
[+] ionCube loader included in Panel installation now supports PHP 5.4.
[+] Global search of APS apps. Panel users can use the global search (in the top-right corner of Panel) to search for available APS applications.
[+] Support for the Roundcube webmail. Roundcube is now the default webmail software for customers.
[+] Predefined list of apps for service plan add-ons. Administrators and resellers can specify the list of apps provided by a service plan add-on. In earlier Panel versions, this was possible only for service plans.
[+] Filter apps by license type. Customers can filter the list of available apps in their Control Panel by the app license type: free or commercial.
[+] Choosing the app version during app installation. Customers can choose the version of an app they are going to install in cases when there are several app versions available in the Application Catalog.
[+] Optional DNS server installation. Administrators can choose not to install the DNS server during Panel installation. In this case, the BIND DNS server will not be installed and Panel GUI will not contain any tools for DNS management.
[+] Optional mail server installation. Administrators can choose not to install the mail server during Panel installation. In this case, only SMTP client will be installed on the server. Thus, Panel and user scripts will still be able to send mail but other mail functionality will be unavailable.
[+] Automatic updating of installed apps. Administrators can turn on automatic updates (Tools & Settings > Application Vault > Update Settings) of all APS apps installed in Panel. If administrators do not force apps updating, customers can turn on automatic updates for a certain app by themselves.
[+] Quick app installation. Users can install apps in one click - the Install button now leads to a quick installation that does not require specifying app settings: Apps are installed with defaults. Nevertheless, custom installation that includes specifying app settings is also possible with the Install (Custom) button.
[+] Support for the APS mail aspect. Panel now supports the APS mail aspect which allows apps to work with the Panel's mail service. For example, Panel mailboxes can be associated with Open-Xchange accounts.
[+] Displaying RSS feeds in the Control Panel. Administrators can configure Panel to display an RSS feed to customers. The feed will be displayed in the right sidebar of the Control Panel.
[+] Support for OpenSUSE 12.3. Panel can be installed on OpenSUSE 12.3.
[+] Support for MySQL 5.5. Panel now supports MySQL 5.5.
[+] Up-to-date third-party components. A number of third-party components used by Panel were upgraded. Panel is now supplied with the following components:
[+] VPS optimized mode indication. Administrators can see the VPS Optimized label in the Control Panel if Panel is running in the VPS optimized mode.
[+] Search engine-friendly site suspension. Site owners can suspend their sites in a search engine-friendly manner.
| Before | Now |
| Suspended sites stop being hosted on the server. Visitors see the web server's default page. | Suspended websites remain hosted on the server. Site visitors are redirected with the 503 HTTP code to the custom maintenance error document page. The former way of site suspension is also possible (it is renamed to Disable). Administrators can define what Panel should do with sites in suspended subscriptions: They can be either suspended or disabled. |
[+] Improved User Interface. The Websites & Domains page is now the default page of the Control Panel (the Home page was removed). Sites are presented in the form of an Active List - with direct access to actions relevant to sites. Each list item for a website is made bigger to display more information and to provide access to relevant operations on the site.
[+] Voting for new features. Administrators can now suggest any ideas about how to improve Panel or vote for ideas of other Panel users. They can open the vote form by clicking the Suggest an Idea button in the navigation pane of the Server Administration Panel. Administrators can also point this button to any other URL or hide it.
[+] Context menu for operations on files in File Manager. Possible operations on files are now grouped in the context menu instead of multiple buttons. Customers can open the menu by clicking the area near the file name.
[+] Notifications about available web apps updates. APS apps warn customers about available updates right on the app settings page.
[+] Support for Horde IMP5. Panel is now shipped with Horde IMP5. In case you upgrade from earlier Panel versions with installed Horde IMP3, Horde will be automatically upgraded to the 5 version.
[+] Support for nginx 1.5. Panel now uses nginx 1.5 for hosting websites.
[*] Customers can set any usernames for auxiliary users.
| Before | Now |
| The email address of an auxiliary user is used as a username for logging in to Panel. | Auxiliary users can have any usernames. |
[*] Administrators can set the path for storing a temporary backup file created when someone downloads the backup from the server.
| Before | Now |
| Panel creates a temporary backup file on the same disk partition with the source backup file. This can cause a backup download failure if there is not enough disk space for storing the temporary file. | Administrators can set an arbitrary location for storing temporary backup files using the DUMP_TMP_D variable in /etc/psa/psa.conf. |
[*] Panel now uses nginx as the internal web server (used to host the Panel GUI) instead of lighttpd.
[*] The visibility of the Hard disk quota parameter to customers is defined by a certain permission.
| Before | Now |
| The Hard disk quota parameter is always shown to customers. | If the administrator did not enable or set the Hard Disk Quota parameter for a subscription, users cannot see this parameter (for example in Websites & Domains tab > Web Users ). |
[*] The docroot directory for subdomains can be specified in API RPC calls using the home parameter.
| Before | Now |
| Panel users can use only the www_root property (of the property node of the subdomain operation) to specify the docroot directory. | Panel users can specify the docroot directory for subdomains using either the www_root property or the home parameter of the add node of the subdomain operation. |
[*] Administrators can turn on Apache piped logs from the Panel GUI.
| Before | Now |
| Administrators can enable piped logs for Apache through the command line. | Administrators can enable piped logs for Apache either through the command line or from the Panel GUI (on the Tools & Settings > Apache Web Server page). |
[*] Panel saves the state of the Hide Domain Aliases and Hide Subdomains options in the Service Provider view. In earlier versions, these options always became disabled after the administrator started a new session.
[*] The tar 1.20 utility is now provided with Panel on RHEL / CentOS / CloudLinux 5.
[*] The Zend framework, which is a part of the Panel installation, was updated to the version 1.11.15.
[*] By default, the support for ionCube is turned on. This is done to provide the encryption of Panel extensions.
| Before | Now |
| ionCube on clean Panel installations is turned off. | ionCube on clean Panel installations is turned on. |
[*] Convenient names of rotated log files. If log rotation is turned on for a website, the names of the created log files will include the creation date.
| Before | Now |
| The created log files are distinguished by numbers in their names. The older logs have a larger number in their names. For example, error_log.1.gz, error_log.2.gz. | The created log files are distinguished by date (YearMonthDay) in their names. For example,error_log.processed-20130101.gz, error_log.processed-20130108.gz. In order to enable dates in log file names, you should add the dateext option into the corresponding section of the log configuration file /usr/local/psa/etc/logrotate.d/<domain_name> |
[*] Migration & Transfer Manager (MTM) improvements. MTM provides more convenient and informative reports on transfer results. Also, MTM no longer shows error messages and warnings when administrators try to transfer an object that already exists on the destination server.
[*] Easy changing of SpamAssassin maximum mail size. Administrators can easily change the maximum size of mail messages processed by SpamAssassin.
| Before | Now |
| The SpamAssassin maximum mail message size is 256000 bytes and administrators cannot change it in Panel for Linux. | Adjusting the SpamAssassin maximum mail message size is performed via the SA_MAX_MAIL_SIZE parameter in /etc/psa/psa.conf. |
[*] Now, Application Catalog does not show APS application add-ons (such as additional languages for WordPress).
[*] Panel saves the state of the search filter on the Domains page in the Service Provider view. In earlier versions, the filter was cleared after the administrator started a new session.
[*] Panel automatically applies all available updates after cloning to a new server.
[*] Support for APS app info links.
| Before | Now |
| APS app info links are not shown. | APS app info links are displayed on the app's summary page (Control Panel > Applications > select an app). |
[*] For the sake of usability, the Websites & Domains is now the first tab in the Control Panel. The Home page is removed.
[*] The AtMail webmail software is no longer supplied with Panel distribution. We continue to support it, so AtMail on Panels upgraded to 11.5 will work as before.
[*] Troubleshooting improvements. Panel error messages now contain links to corresponding Parallels Knowledge Base articles.
[*] Apps available for installation in the Control Panel are now sorted by their ratings and number of downloads. In earlier Panel versions, apps were sorted alphabetically.
[*] Improved app search in service plan settings. The search field on the Applications tab of service plans and add-ons now supports type-as-you-go searching.
[*] Improved app appearance in service plan settings. Now, commercial apps (on the Applications tab of service plans and add-ons) are marked with the $ image.
[*] Improved app appearance in the Control Panel. Now, it is easier to work with the list of available apps on the Applications tab of the Control Panel due to a couple of improvements:
[*] Optional update of third-party components. Administrators can apply Panel updates without upgrading third-party components (in case the update includes such upgrades). This can be set on the Tools & Settings > Update and Upgrade Settings page or through the API RPC call. Parallels Installer also supports this option: ./parallels_installer... --select-product-id plesk --select-release-current --upgrade-installed-components --include-components-from-class vendor=parallels --include-components-from-class patched.
[*] Security improvements.
[*] PHP used by sw-engine (used to run Panel) is upgraded to the 5.4.14 version.
[*] Administrators now see the name of the mail server that is currently running in Tools & Settings > Mail Server Settings. In addition, now this page contains a link that allows to quickly switch to another mail server (for example, from QMail to Postfix).
[*] Administrators now see the estimated connection speed between the source and destination servers during data transfer in Migration & Transfer Manager.
[*] More available system utilities in the chroot environments. A number of utilities used for downloading and unpacking archives are now available for customers who work in a chroot environment.
| Before | Now |
| No utilities for downloading and unpacking archives are available in a chroot environment. | wget, zip, unzip, gzip/gunzip, tar, curl are available in a chroot environment. |
[*] Improved logic of the mchk utility. The mchk utility now preserves custom mail handlers created by administrators.
| Before | Now |
| The mchk utility removes custom mail handlers during mail settings restoration. | The mchk utility preserves custom mail handlers during mail settings restoration. |
[*] Improvements on the Applications tab. Customers can now sort the list of available apps (on the Applications tab) by category or their popularity.
[*] Websites in the maintenance mode are now restored in the Suspended state after the transfer from earlier Panel versions.
[*] Improvements in regeneration of web server configuration. When the administrator regenerates web server configuration, Panel excludes virtual hosts that can cause problems on the web server start.
[*] Improvements in Control Panel. The Users tab is now made one of the last tabs in the user interface as it was not often used by customers.
[*] The built-in Presence Builder tool now uses the same protocol (HTTP or HTTPS) with Panel. In earlier Panel versions, Presence Builder always used HTTP; even if a user communicated with Panel over HTTPS.
[*] Access to log files over SSH or FTP for customers. Customers can now access log files of their sites over SSH or FTP. The logs are located at /var/www/vhosts/domain.tld/logs.

[+] Affiliate Programs. Providers can involve existing customers in promoting their hosting offers. For each new customer, affiliates receive a commission and can use it to pay their services or claim the payout by check.
[+] DNS Hosting. Business Manager can host DNS zones of domain names purchased through it on connected Panels. Please note that not all domain name registrars support this feature.
[+] Security improvements. Customer & Business Manager 11.5 introduces multiple security improvements:
[+] Performance improvements for online stores. Online Store performance is greatly improved. The page for domain names lookup got the most significant performance improvement.
[+] Upsale plans. It is much easier for providers to upsell additional services to customers – just define that one plan is an upsale for another and online stores will suggest a potential customer to buy them both. This is a great opportunity to sell more SSL certificates, web apps, or support services.
[+] Improved appearance. Now, Customer & Business Manager uses the same UI skin as Parallels Plesk Panel.
[*] Improvements in subscription status management. We removed useless subscription statuses and added a tool that allows administrators to change statuses and keeps them synchronized with respective Panels.
| Before | Now |
The set of subscription statuses is the following:
|
The set of subscription statuses is the following:
|
[*] Quick subscribing to plans with zero prices in online stores.. Now, subscribers do not fill in the payment details if the price of their order is zero.
[*] Immediate provisioning of new subscriptions. The new task manager enables CBM to start provisioning a subscription immediately after the payment is processed.
| Before | Now |
| Provisioning tasks run once in a certain period of time. Thus, customers cannot access their subscriptions right after they pay their invoices. | Provisioning tasks start immediately after the corresponding payment is received. |
[*] Manual refunding of gateway transactions. Now, providers can refund credit card transactions manually, for example, by check or cash, and mark the transaction as refunded without processing the refund through the gateway.
| Before | Now |
| If a provider needs to refund a payment received through a payment gateway, they should process the refund through the gateway. | Providers can refund gateway transactions outside the gateway and mark the transaction as refunded manually. |
[*] Improved processing of declined transactions.. Customer & Business Manager 11.5 lets providers define how to process gateway transactions that cannot be completed, for example, because of insufficient balance.
| Before | Now |
| If the system fails to charge a credit card, it keeps trying to do this until the transaction is successful. | Administrators can define how many attempts to charge a credit card the system should do and how much time it should wait between two consequent attempts. |
[-] Customer & Business Manager did not apply taxes to custom invoices.

[+] Switching off editor's modules. Providers can make certain modules of the editor unavailable to their customers.
[+] Changeable background width. Users can make backgrounds of page areas elastic, leaving content width the same. This allows design studios and users to create diverse and unusual designs.
[+] Site owners can use many fonts from the Google Web Fonts library. These additional fonts are now selectable in the Text & Images modules.
[+] Extended support for editor rebranding and white-labelling.

* – shipped with the Panel distribution
** – by default, PHP is installed from the repository of the OS vendor but you can use an alternative repository. Starting from 11.5, you can also install multiple PHP versions.
Panel 11.5 supports upgrade from the following earlier versions:
'/etc/init.d/boot.apparmor stop'
'update-rc.d -f apparmor remove'
If you are using CloudLinux 5.5 or earlier, be sure to install the following package versions (or later) from http://repo.cloudlinux.com/cloudlinux/5.5/updates/:
If you install other versions of these packages, the Panel might be inoperable.
We recommend that you read information about the product installation, upgrade, or migration before you start deploying Parallels Plesk Panel. This information, including detailed instructions, can be found in the Installation, Upgrade, and Migration Guide located at http://download1.parallels.com/Plesk/PP11/11.0/Doc/en-US/online/plesk-installation-upgrade-migration-guide.
Parallels Plesk Panel Knowledge Base can be accessed at http://kb.parallels.com.
The upselling method in Try and Buy scenario no longer works on Panel integrated with Customer and Business Manager.
When upgrading or migrating to Panel 11.5 from earlier versions, remember that service plans that allow traffic overuse can be successfully upgraded or migrated only if the overuse billing feature has the following settings:
After upgrading or migrating, such plans will have the following settings in Panel 11.5:
If service plans that allow traffic overuse have other settings, then after upgrading or migrating, Business Manager will disallow the pay-as-you-go hosting for them and stop charging subscribers for traffic overage.
When working with Presence Builder through the Safari browser on Windows, the users might encounter issues with uploading to their sites multiple images or documents at once. In such cases, we recommend uploading them one by one.
You need to use the latest version of Parallels Installer for performing upgrades to Parallels Plesk Panel 11.
MySQL server may hang during installation. If you encounter this issue, stop the installation, restart MySQL, and then start installation again.
If you want to install Miva applications on 64-bit Ubuntu Linux systems, then you also need to install 32-bit openssl libraries and specify the proper installation paths in the /etc/psa/psa.conf file, as LIB_SSL_PATH and LIB_CRYPTO_PATH values.
Make sure that your Panel license is valid before you attempt to access Customer & Business Manager. Learn more in http://kb.parallels.com/en/111604
Apache configuration can be broken in case Business Manager requests to create Panel subscriptions in bulk. Learn how to repair the configuration in http://kb.parallels.com/en/111605
You should specify a mail server you currently use with Panel when upgrading Panel through Virtuozzo templates; otherwise, the upgrade will fail. For details, see the KB article http://kb.parallels.com/en/11183.
Before you uprade from Plesk 8.6, ensure you have the latest version of PVC. For details on problems you encounter if you use prior versions of PVC, see http://kb.parallels.com/en/11186.
To use spam protection based on DNS blackhole lists for IPv6 addresses, you should have Postfix v.2.6 or later.
hMailServer 4.x is not upgraded because Panel 10 does not support this mail server. For a workaround, refer to http://kb.parallels.com/en/9602.
On operating systems of the SUSE family, Apache web server may fail to start/restart with the "could not bind to address [::]:443" error because some other process is using the 443 (80) port. For details on the problem resolution, refer to the KB article at http://kb.parallels.com/en/1507.
If web server fails to start and you see the lines "Unable to open logs" in the web server's error log file, then it means that the number of allowed open file descriptors is not enough for the number of hosted domains. In such a case, increase the number of file descriptors. You can use the following formula to calculate the required value: number of domains * 2 + 1024. The maximum possible value is 65536. To set the required value, use the ulimit -n <number> command.
Because of a bug in Mailman 2.1 software, mass addition or removal of mailing list subscribers might not work properly. To resolve this, you can switch off email notifications by inserting the following lines into Mailman configuration file /etc/mailman/mm_cfg.py:DEFAULT_ADMIN_NOTIFY_MCHANGES = No
DEFAULT_SEND_WELCOME_MSG = No
DEFAULT_SEND_GOODBYE_MSG = No
Presence Builder does not support custom Panel skins. Installing a custom skin to Parallels Plesk Panel 11 may break certain functions of the Presence Builder editor.
Presence Builder does not support the STRICT_TRANS_TABLES mode of MySQL. Administrators who use this mode and want to continue using their MySQL installations with Panel should switch this mode off by adding the following lines to the my.ini configuration file before installing Panel: #sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
Safari users may encounter issues with posting comments on websites that use the Commenting module. This happens if "Authorization with a Facebook account" is selected by the webmasters in the module settings.
