Access denied for user 'violate1_pumpmoonshotdb'@'localhost' to database 'PumpmoonshotDB'

Cannot select database

The database server could be connected to (which means your username and password is okay) but the PumpmoonshotDB database could not be selected.

Are you sure it exists?
Does the user violate1_pumpmoonshotdb have permission to use the PumpmoonshotDB database?
On some systems the name of your database is prefixed with your username, so it would be like username_PumpmoonshotDB. Could that be the problem?

If you do not know how to set up a database you should contact your host. If all else fails you may find help at the WordPress support forums.
