Some members reported they get logged out randomly, i started investigating and i have found the problem. For example if you go to www.colonial-forces.be and log in it's fine. However if you go to http://colonial-forces.be you are no longer logged in. If you place www back it's fine. I tried looking for a fix here but no luck. I have had this problem with vbulletin aswell, i had to change something with the cookie domain.
