If you've logged into your PHPMyAdmin webapp and cannot find certain features such as the Designer tab, for example, look to see if you notice the following message displayed within the interface:
The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated.
To enable all features, you must first log into your DirectAdmin server as the root user via SSH (remember that Knownhost uses port 2200 by default to limit SSH bruteforcing) and run the following commands:
cd /root wget -O create_tables.sh http://files1.directadmin.com/services/all/phpMyAdmin/create_tables.sh chmod 755 create_tables.sh ./create_tables.sh
Running these commands will download the create_tables.sh script, which will create the da_phpmyadmin user and password as well configure the config.inc.php file.
