User can create a database from phpmyadmin

The limit of the package for MYSQL databases is set to 1 but when I'm going to php phpmyadmin the user can create a database from there

They can do it from their computer, or you are testing and able to do it.  Because If I log into phpmyadmin from CWP, then switch to a user account and load from there, I stay logged in as root.  JS
