Hello,
Sorry to hear you're having problems with creating a new MySQL database. Unfortunately, without more information about your account - a URL at least, we can't determine where the problem is occurring and then take action on the problem. Make sure that you have covered all of the steps in creating a database using MySQL in cPanel. If you continue to have problems, then please contact our live support team for further assistance (or if you wish to handle this issue in private- posts to the Community Support web page are public).
Regards,
Arnel C.
