If you cannot connect to the MySQL server, this might happen due to several reasons:
Incorrect MySQL hostname. The MySQL hostname on most of our servers is localhost (with the exception on few reseller servers). You can always double check this information in your Members area -> List accounts -> Account details.
Incorrect MySQL username / password or database name. Please navigate to cPanel -> MySQL to check this information. If you cannot remember what password is set on the MySQL user, feel free to delete it and recreate it one more time.
- You have not added the MySQL user to the database. This is a very common issue that people forget to do. In order to have a fully operational MySQL database you must also add a MySQL user to the MySQL database and assign full permissions. You can achieve this by clicking on the 'Add' button under 'cPanel' -> 'MySQL Databases' -> 'Add User To Database' section. If you have any other issues with the MySQL connection after taking these steps, please let us know.
