Thanks a lot for your help but none of it worked.

I did exactly what was told in the thread.
Isn't there another way to add costum pages which will definitely work and will be accessible for everyone? It's just that the template must be similar to the rest (and changes along with the rest if I would edit it). The only difference is the content within.
If it would be possible to have a guest be redirected to the logged in system as well it would be the best!
Thanks.
