Good (early) evening guys..
I want to put up a new forums and it worked out quite well yet. I have just recognised when I press "New Thread" I get an Error saying "Invalid Forum". Tried to make a new category with a new forum and I got the same error there. I then changed theme to Default and everything works fine again.

Is there any common solution for that problem?

Added the theme to attachements.

Kind regards,
Nightmare
