• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

    Question Ubuntu 26 Support

    I noticed that the changelogs of several Plesk extensions already mention support for Ubuntu 26. However, according to the official Plesk system requirements, Ubuntu 26 is not yet listed as a supported operating system. So I was wondering: Is Plesk already working on Ubuntu 26, even though it...

    Question DDoS Attack on Plesk Server +

    @King555 That's correct. I misread that. Nevertheless, I would still check whether my assumption is correct and which domain the attack is targeting, so that we can recommend further measures.

    Forum timezone setting – automatic daylight saving adjustment is missing

    I noticed that the Plesk Forum apparently does not provide an option to select a dynamic timezone such as Europe/Berlin. For Germany/Berlin and many other countries, the UTC offset changes depending on daylight saving time: Winter (CET): UTC+1 Summer (CEST): UTC+2 Since the forum settings...

    Question SFTP access for additional FTP accounts – Public Key authentication?

    @Sebahat.hadzhi thank you for your response. That’s very unfortunate, as setting up SSH users with the appropriate system-level access permissions is quite complicated and time-consuming. I had hoped the new system would offer more in this regard. As it stands, I’m struggling to see the real...

    Question Disable Email Forwarding

    I just wanted to remind everyone at Plesk that this issue continues to affect a large number of server administrators. Forwarding emails to external domains often causes significant problems, and this is likely to become even more common in the future. Many email providers are continuously...

    Question Can TuxCare ELS install older PHP versions on a new Plesk server?

    I have now successfully used the TuxCare PHP extension and have to say: it works really great Sometimes it’s good to give praise instead of only speaking up when there are problems. However, I did run into a small issue: I had to manually create the directory `/var/lib/php/session`, as it was...

    Question Plesk Migration – Webmail Signatures and Contacts Missing

    We recently migrated a Plesk server to a new environment via Plesk Migrator Extension. The migration itself was successful — mailboxes and emails have been successfully transferred. However, after the migration, Roundcube signatures, identities, and personal address books were not transferred...

    Resolved Mailbox storage usage displayed incorrectly in Plesk

    @lukas-degan I had exactly the same issue with other mail accounts, too. That’s why I do believe it’s a bug, but I’m missing information on how it can occur. As a workaround, the only thing I can suggest is renaming the mailbox, creating a new one with the old password, and transferring the...

    Question Can TuxCare ELS install older PHP versions on a new Plesk server?

    Thanks for the explanation. One more question: does it have to be the official PHP version provided by Plesk, or could I also install PHP 7.2 from an alternative source and add it to Plesk, and then use it with the extension afterward?
