I am having a very strange problem. There are several posts on my discussion forum to which I can’t reply. The system thinks I am not logged in and will not allow me to login. I just keep getting the login page over and over again. But this problem is not happening across the board. I am able to login to the administration site, and I am able to login and reply to other posts. I have no idea why this problem is only happening with certain posts. Anyone?
