Ok, I have found out that this mod is working very well on my live forum even thought I haven't sorted out search.php yet. That's not important as I removed the mod again after discovering that it makes my front page unusable.
I'm running Textpattern with a modification for including comments after articles and such (From phpBB3). I'm not much of a coder myself, but I bet it is including common.php at least. The problem is that i get this error on my front page:
Fatal error: Call to a member function acl_get() on a non-object in /home/users/juvenorg/www/forum/includes/functions_karma.php on line 70
I know this isen't a bug or a problem with the modification, but perhaps someone has a method or workaround for my problem? Untill then, this mod can't be used by me unfourtantly.
Thanks for a great mod anyway. It worked fine while testing.
