grouping works like a charm. But if i try to remove the grouping via headermenu i get an SQL Error.
Like: SQLSTATE: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near ‘bearbeiter desc LIMIT 0, 500’ at line 3Could not execute query!!!
It happens at all my grids (all columns), no matter what kind of data.
