Plugins and Permissions updates Warning. Spent a morning dealing with a silly issue so wanted to warn everyone about it. The current implementation of permissions uses an ajax post that looks for "ACK" as a response on line 1. When I built my plugins I inadvertently ended my code with CODE ABOBE ?> <------- Blank Line END OF PAGE Tiny mistake but the knock on effect is that when pages are rendered the blank line is added. The ajax script for permission expects the ACK response on line 1 and doesn't look anywhere else. As such if you make this mistake you will break permission updates. Sympton: No error on post back but get back a small pink/red bar when Verifying permissions. Hope this saves others a big headache and Denis may be worth tweaking the ajax code to be a little more open to blank lines or bypass local.php perhaps.

I have just committed the change necessary to use class methods as callbacks, it will be available in the next version. -- Denis Ovsienko
