• 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.

Basic Pleskian
Hi folks!

In past 10 days I was having issues with my memory usage on my server. one of the things I did was to change from FPM application served by Apache to FPM application served by + nginx. Also added extra memory capacity so the webserver (and sites) are up & running again.
Now the following is happening when I go to webmail.domain.com it throws the following error

Internal Server Error​

The server encountered an internal error or misconfiguration and was unable to complete your request.

Please contact the server administrator at [no address given] to inform them of the time this error occurred, and the actions you performed just before this error.

More information about this error may be available in the server error log.

Any clues?
