I'm getting this error when trying to add a moderator:
Couldn't update private forum permissions
DEBUG MODE
SQL Error : 1064 You have an error in your SQL syntax near ' 1, 1, 1, 1, 1, 1, 1, 1, 0)' at line 2
INSERT INTO forum_auth_access (forum_id, group_id, auth_read, auth_post, auth_reply, auth_edit, auth_delete, auth_sticky, auth_vote, auth_pollcreate, auth_mod) VALUES (13, , 1, 1, 1, 1, 1, 1, 1, 1, 0)
Line : 379
File : /hosted/schangar/forum/admin/admin_ug_auth.php
I think this error has something to do with the blank value for group_id.
