When you notice you can’t create more database in your web hosting, you may have reached the amount of databases you can create for the web hosting plan.

We advise you upgrade your hosting plan to a higher one to widen the limitations. But if you’re in low budget to upgrade to a higer web hosting plan, then you should delete some database. Here is the steps how you can delete your website database:
Login to your C-panel, and search Mysql database. Suggested at the first roll.
Now get into Mysql database area. There you’ll notice your web site database(s) and username(s). Each database has it username which both registered with. So if you should delete one you should for another.
I want you to select the database and username which you don’t use, and delete, hit the red delete button and confirm deletion of Mysql database then Username.
By following the instructions, you’ll ease up database space for a new database.
