MariaDB is a fork of MySQL. The database structure and indexes of MariaDB are the same as MySQL. This makes MariaDB a backward compatible, drop-in replacement for MySQL. We currently run a combination MariaDB version 10.6 and 10.11 To check the version of MariaDB: Head to Login to Hosting, then phpMyAdmin. Select the database in the left-hand panel. Select the Query tab at the top. Type the query: SELECT VERSION(); and select Go. The version of MariaDB will then be outputted.
