Anyways, I gave up and re-made the whole thing.

Seems like it works now.

Hello. I got this problem here, that my board index link is linking to / instead of /index.php This is not really nice as you manually have to insert the index.php every time you want to see the forums.. Where do I change this? the {U_INDEX} is set to index.php in functions.php - it just doesnt link...
