• Hi, Pleskians! We are running a UX testing of our upcoming product intended for server management and monitoring.
    We would like to invite you to have a call with us and have some fun checking our prototype. The agenda is pretty simple - we bring new design and some scenarios that you need to walk through and succeed. We will be watching and taking insights for further development of the design.
    If you would like to participate, please use this link to book a meeting. We will sent the link to the clickable prototype at the meeting.
  • (Plesk for Windows):
    MySQL Connector/ODBC 3.51, 5.1, and 5.3 are no longer shipped with Plesk because they have reached end of life. MariaDB Connector/ODBC 64-bit 3.2.4 is now used instead.
  • The Horde webmail has been deprecated. Its complete removal is scheduled for April 2025. For details and recommended actions, see the Feature and Deprecation Plan.

    Be careful with MariaDB 80% memory usage of your RAM. Especially in the midday hours, more traffic can occur on your server and more PHP "workers" can be started, which use up additional RAM.

    Question Can i use MariaDB 11.x with Plesk 18.0.57?

    I understand the long term support mindset. Okay, the advantage is of course that Plesk updates it alone. - MariaDB 11.2.2 Release Notes - MariaDB 11.0 – new optimizer, new major version series - MariaDB.org - MariaDB Would Plesk also update from MariaDB 10.11.x now LTS (Long Term Support) to...
