Unable to connect to database server

This either means that the username and password information in your settings.php file is incorrect or we can't contact the MySQL database server. This could mean your hosting provider's database server is down.

The MySQL error was: User dbo462223623 already has more than 'max_user_connections' active connections.

Currently, the username is dbo462223623 and the database server is db462223623.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.
