if you are using MariaDB you will likely see everything work (including all in game functionality) but the bans page will be blank. the error is below.
To resolve this, i simply commented out line 77 from adodb-errorhandler.inc.php which uses a function that exists in MySQL 5.6 but is not supported in MariaDB. Keep in mind MariaDB and MySQL are no longer 100% compatible since the release of MySQL 5.6 and this is by design.
you probably shouldn't do this
