• 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.

As logging into all websites, it is required to have users and passwords. As accessing website Parallels Panel 10.4 on server, there is the indication of the following error:

HTTP Error 500.0 - Internal Server Error

Would you mind helping to figure out the errors' reason, and the solution?

Thanks with regards,

I have a very similar problem. I wonder if there was something in the last update that caused this?
 
Looks like that this server has insufficient memory. Consider possibility for increasing the amount of RAM on the server.
