• 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.

Issue AH01071: Got error 'Primary script unknown' happens every few days

Hi everyone,

I never had this issue before but since upgrading to Plesk Obsidian this error happens every few days. It might not even be related to the upgrade but I just can't tell at this time.

The website error log shows:

AH01071: Got error 'Primary script unknown' - Apache Error

The websites on php just show "File not found"

The strange thing is that all services are running. A reboot fixes it but then a few days later it happens again.

Plesk Obsidian running on CentOS7 converted to CloudLinux.

Thanks
