I'm having issues too and I'm using IE 7. I'm having problem to keep me log even on the same computer. I log with the option keep me loged then I close my browser and I have to relog again if I go back on the forum.
I think I've found something that could be the cause of my problem and I wanted to ask someone about it.
I'm using port 80 redirection from a DNS service provider (
www.no-ip.com).
I think it may be the reason why I have these problems. I'll try to access my server without using the port redirection to see if I still have the problem.
Meanwhile, I would like someone to confirm me that it might be the cause of my problems.
Thanks !
