• 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.

Plesk 10.2 Backup Manager "Error 500" issue

Hello,

I was trying to upgrade a client's Plesk from 10.2.2 to 10.4.4, but it failed. As a first step to troubleshooting, I attempted to make a backup of the site (Server> Tools and Utilities> Backup Manager). However, whenever I do this I get the error:

"500 - Internal Server Error There is a problem with the resource you are looking for, and it cannot be displayed."

Another issue that might be related is that I get certificate errors when going to the page. I am taking over this project from another person, so I don't know if this has been an issue or if it's new.

Info:

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE:

Parallels Plesk/ 10.2.2/ Windows Server 2008 R2 Standard/ 64 Bit

PROBLEM DESCRIPTION AND STEPS TO REPRODUCE:

See above

ACTUAL RESULT:

EXPECTED RESULT:

Successful Backup and Upgrade

Thank You!
