bbPress.org

I get this error at the top of the pm.php page:

bbPress database error: [Unknown column 'del_receiver' in 'where clause']

SELECT * FROM bb_privatemessages WHERE id_receiver = '1' AND del_receiver= '0' ORDER BY created_on DESC



bbPress database error: [Unknown column 'del_sender' in 'where clause']

SELECT * FROM bb_privatemessages WHERE id_sender = '1' AND del_sender = '0' ORDER BY created_on DESC

Also, all previous Private Messages are missing.
