I've setup a database in mySQL configured the wp-config.php with the correct user name and password, however no matter what I set the DB_NAME to it won't connect.
I have tried the variations of the DB_NAME with and without the prefix, recooted the server and now am at a loss???
We were able to connect to the database server (which means your username and password is okay) but not able to select the oppenheimergroup_com_-_mortgage-websites database.
Are you sure it exists?
On some systems the name of your database is prefixed with your username, so it would be like username_wordpress. Could that be the problem?
