I've tested without this hooks, it's a hook for displaying a search when a topic is deleted.
I've tested with the default theme.
After the error was on another hook
The last error without them :
Error: Call to a member function hidden() on null (0)
#0 /www/applications/forums/modules/front/forums/topic.php(143): IPS\Content\_Item->commentForm()
#1 /www/system/Dispatcher/Controller.php(101): IPS\forums\modules\front\forums\_topic->manage()
#2 /www/system/Content/Controller.php(50): IPS\Dispatcher\_Controller->execute()

It's a realy random problem. For reproduce it, i've open some topics and i post some messages. On some topic the error is generated.
Point on a forum with error :
Topic: 0
Post: 2
POINTS FOR TOPIC STARTER PER REPLY: 0
I've tested with Rewards & Logs, Bank and Statistics apps disabled, but i have the same problem, and I have log on admin cp.
I've tried to disable "Point for forum" but i have the same problem
if you don't have an idea, i will try on another install with all plugins and apps disabled
