I'm on this thread because "Essential Links" at the top said this is where to bring "bugs, problems, suggestions" and there is no other thread that seemed appropriate.
For a few days now I keep having the experience of trying to post a message and being sent to the log-in page instead, although my name is on the list at the top as being logged in. This happens even if I log in again, and even if I log in many times. I've lost some posts because of it but then I learned to copy and save them. Sometimes if I log in and log out a number of times a post will go through but not always. Sometimes if I reboot the computer the problem may go away but not always. Eventually something resets and I can post again but I don't know what happened to make that possible.
Sometimes I have more than one page of EvC open when I'm looking up old posts, and sometimes one is logged in and the other isn't so I've thought that could have caused the problem, but the problem persists even when only one page is open.
This time I tried almost a dozen times doing this and that until I could finally post without being redirected to the log in page, and as I said, I have no idea what action or combination of actions finally cleared up the problem.
Now I'm copying this message and pasting it in my email in case I lose it.
It does sound like a cookie problem. Log in credentials are stored in cookies. My guess is that you've managed to get cookies stored under both "evcforum.net" and "www.evcforum.net". Both the webhost and the software force accesses to "evcforum.net" to morph into "www.evcforum.net", but I suppose it could still happen.
You use Internet Explorer, and I'm on my Mac right now and can't check out the cookie deletion details of IE. If you know how, delete all cookies associated with "evcforum.net" (enter "delete cookies ie specific" into Google for instructions). If you don't know how then just delete all cookies, which has the drawback that you'll have to log in to all websites again.
