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: Access denied for user 'db27133'@'%' to database 'db27133_devfundraisers'.
Currently, the database is db27133_devfundraisers. The username is db27133 and the database server is internal-db.s27133.gridserver.com.
