Doesn't login?

This problem has been going ever since I registered in this new forum, I did notice but I didn't really think it was too much of a big thing to complain about..but after going on the forums about 100 times it's now getting annoying.

Ok, so when I go onto the forum it tells me to login...but I set it to stay logged in. I have to keep logging in every time. But it gets weirder..
If I haven't logged in but I click on anything in the website (eg, a topic or another mini forum thing) then at the top right it says I'm logged in.

So I'm logged out in the homepage but if I click on any link I'm automatically logged in until I quit the internet. 
Any suggestions?

Edit: Reloading the page doesn't log me in, only clicking on a forum. Even when I click on the "login" button then at the top right of the screen is shows that I'm logged in!

did you try to delete your cookies for everything nifflas.ni2.se ? Do you even have cookies enabled?

Umm, I'm using Mozilla and I did "clear all history" and there is a button to delete all the cookies and I did that, but nothing happened. It still doesn't log in.

um..you weren't supposed to delete the cookies, the point is to save them..

Try clearing all the cookies from the control panel (if you using windows).

I dont know, but CTRL+F5 could help  , and if not, This is werid.

What does it do?

I know the f5 but why ctrl?

F5 refreshes the page. F5+CTRL bypasses the cache, which forces the browser to get the most update information from the server it is contacting, thus allowing (in many situations) you to fix a problem or update the page if your cache was preventing it. Very useful.

Ctrl+F5 doesn't work...

Firefox sucks

Did you cleared the cache and cookies and so, and then quit all the browsers you had open?

This indeed sounds either like a cookie problem but even more likelly a caching problem. Clearing your temporary internet files should solve that.

Do you have a proxy server on your end? If so, see if you can clear its cache.
