• 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.

Repairing Plesk software even rebooting or shutting down then turning it back on doesn't work. This appears to be a bug so why it is doing this? if you have anything to fix this please tell me.
 
SOLUTION

Copy common_func.php3 from C:\Program Files\SWsoft\Install\070705.17\Plesk831.cab
to C:\Program Files\SWsoft\Plesk\admin\plib
