MySQL and MariaDB applications normally use three related pieces of information: a database, a database user, and the privileges that allow that user to access the database.
Creating a database does not automatically give every database user access to it. The user must be assigned to the database with the privileges the application requires.
cPanel may prefix database and database-user names with the cPanel account username. Applications must use the full names shown by cPanel.
Use Database Wizard for a first database/user setup and Manage My Databases for ongoing management.
