Website down - MariaDB failed

[magi_gr]

Hello.I had a working website for 2 years, which suddenly stopped working. I haven't performed any updates or upgrades. When I woke up, I noticed that it was not functioning.

I contacted my hosting provider, who informed me that the problem was not on their end. However, they checked the issue for me and provided the following response:

The issue is that MySQL cannot find the table of plugins 'mysql.plugins'.

I am using OpenLiteSpeed with MariaDB, on Ubuntu 20. OpenLiteSpeed shows as active and running, but MariaDB shows as failed.
