My dropdown menus don't work (search forum, main options).

I've read several post about it, and they all say I should have <{$xoops_module_header}> in theme.html. Well, I have it, and I still don't have them...

I've also tried setting the cache for the module to 1 hour, and no cache, and still nothing...

Should there be something special in my templates?

When I look into the generated code for my forum pages, the <{$xoops_module_header}> doesn't seem to be generating any code at all.

What am I doing wrong?

Here's a link to my forum:
