We were able to connect to the MySQL database server (which means your username and password are okay) but not able to select the database.
The MySQL error was: No database selected.
Currently, the database is . The username is dbo483495651 and the database server is db483495651.db.1and1.com.
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.
