In GForum/Post/Write.pm replace lines 370-379 (at least with EditPlus) with:
Code:
unless ($USER->{user_forum_permission} >= FORUM_PERM_MODERATOR or ($USER->{user_id} == $post->{user_id_fk}
and
$post->{forum_allow_user_edit} % 2 # 1 is edit, 3 is edit & delete, but 0 and 2 do not allow editing
and
(!$post->{forum_edit_timeout} or ($post->{post_time} + $post->{forum_edit_timeout} * 60) > time)
)
) {
return GForum::do_func('permission_denied');
}
