I am getting the issue today and mariadb is not starting, upon investigating the issue I was getting mariadb corrupt table, so I insert
innodb_force_recovery = 5
into the my.cnf file. what it did was, all my site are up.
but now, I am getting issue with cwp admin login. so I reset the mysql root password, it was successfully reset, and also change the root password, but still getting the above message
