Ok I have a new problem with my site, It's hard to explain, but I will try.

I host my site on my own server, but I have domain-forwarding to my server. Then I use the my domain name, users can't register. Got this message: "No valid security token found in session"

I have noticed that happens because my domain provider open my site in a frame;

Visit my site and choose view source and see what I mean.

http://www.hipooniosamigasite.org/register.php

And you can't register. But if your use http://hipooniosamigasite.ath.cx/hipoonios/register.php then it's working.

Another problem is, Sometimes my theme looks crap in Mozilla/Firefox, then I use the domainname. Newer happens when I use the ath.cx

I don't want to use the free ath.cx services then I have paid for a .org domain. Please help me.

Hi
It pays to use the search button. A search on valid security token gave this thread

I suggest you look into cookies, firewalls and nortons security on FAQ. Any of these might provide the answer you are looking for.

As for the way a page renders - sorry - but once again i suggest using the search feature.
