We were able to connect to the database server (which means your username and password is okay) but not able to select the n16bf45_mensheadlines database.
n16bf45_mensheadlines have permission to use the n16bf45_mensheadlines database?username_n16bf45_mensheadlines. 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.
