Problem: DHTML gets turned off

[Sjakie]

Somehow on my forum the function DHTML function gets turned off. When I look at the option in the options menu, It's still switched on?

For instance: When I push the quicklinks button I'll be sent to the top of the page and the drop down menu doesn't come any more.

I've fixed this by turning the "Plugin/Hook System" on/off. Then it worked again.

So it has to be one of my installed products that's causing the problems. But I can't seem to find which one.

These are my installed hacks:
