Grouper - Documentation

A database query failed. The error message will give you more information about what Grouper was trying to do when the query failed.

The database name or tables name in your configuration don't match your actual database: Compare your configuration (in grouperconf.php or the page where you're displaying the feed) to the database and its table to ensure that they match and fix any discrepancies.
Something is wrong with your database: Fix your database software or your database tables.
