Symptoms

Plesk servers show outdated/unsupported error message:

"servername.plesk.page is either running an unsupported Plesk version (earlier than 18.0.47) or the Plesk installation is misconfigured"

Bug with ID MC-11291.

Consider updating Plesk to the latest releases because Plesk Obsidian 18.0.72 and 18.0.73 are not affected by this issue.

Note: error message might be ignored because servers continue the correct work.
