Resolved Plesk Monitoring = An unexpected error occurred

[Protogon]

I have the same problem on two servers (Centos 7.9 and Ubuntu 22.0.4) with plesk 18.0.60. This started around the latest ..60 update and at the same time upgraded to MariaDb 11. Tried to remove/reinstall Monitoring and Grafana and Plesk repair all. Nothing worked. Any solutions?
