Замечательно работал внутренний сайт в связке mysql+drupal, но в один момент выдал (при подключении)

Warning: mysqli_error() [function.mysqli-error]: invalid object or resource mysqli in /var/www/masia/www/includes/database.mysqli.inc on line 104

Warning: Cannot modify header information - headers already sent by (output started at /var/www/masia/www/includes/database.mysqli.inc:104) in /var/www/masia/www/includes/common.inc on line 141
Unable to select database
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: .
Currently, the database is intavto. The username is intmasja and the database server is localhost.
• Are you sure you have the correct database name?
• Are you sure the database exists?
• Are you sure the username has permission to access the database?
For more help, see the Installation and upgrading handbook. If you are unsure what these terms mean you should probably contact your hosting provider.

Не подскажите в какую сторону рыть?
