Access denied for user 'macoopfrjtnew'@'%' to database 'macoopfrjtnew'

Can’t select database

We were able to connect to the database server (which means your username and password is okay) but not able to select the macoopfrjtnew database.

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

If you don’t 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.
