MariaDB change data directory location

Hi,

I'm trying to change the MariaDB data directory from /var/lib/mysql to /my_folder/mysql.
Everything is good I can log into mysql in command line but plesk give me a hard time with Zend Errors.

I've change my /etc/my.cnf and my /etc/psa/psa.conf to match with the new mysql location but still get problems.

Did I have to change something else or reconfigure something?

Here's the error I get when trying to access my server :


ERROR: Zend_Db_Adapter_Exception: SQLSTATE[HY000] [2002]...
