After I uploaded the forum module, editview and listview works, but when I tried to search based on title and user, it didnt work and I got this error message: "Error running count query for Threads List: Query Failed:SELECT count(*) FROM threads LEFT JOIN users ON threads.created_by=users.id where threads.deleted=0 and threads.title like ('%%') AND created_by IN('7a43731b-86e6-703f-b66b-45021dbf23b1') AND (threads.deleted=0)::MySQL error 1052: Column: 'created_by' in where clause is ambiguous" What will I do about this? Please help?...
