• Debian 11 has reached its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.81 is 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.

Regular Pleskian

***Licensing Error You have exceeded the number of customer accounts you can have in the system. Please upgrade your license.


Upgrade appeared to complete, however CPU usage was high and SSO broken. After reboot CPU usage down and SSO seems to be using proper port of 8443 instead of 11443.

however, there seems to be z problem with the business manager license. See above error message.
