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: 'dbo269407597@%' to database 'db269407597'.
Currently, the database is db269407597. The username is dbo269407597 and the database server is db1825.perfora.net:3306.
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.
