I wrote a discussion board that uses cookies and sometimes the pages load fine when I'm logged in, but then it will suddenly not load the same page even though the page hasn't changed. I get 500 errors and sometimes 404 errors. If I delete the cookie (which logs myself out) it goes back to working fine. There are times I can browse the board, make a few posts, and several pages later the problem happens. Other times, I can't go far without it happening. Some other users said the same thing happens to them, and some say it never happens to them. Nothing like this ever happened when I was testing it. All I did was change the folder and I updated and tested the cookies on each page. I never had this problem while testing it. Do you know how to solve this problem? Have other users seen this problem elsewhere? I'm using MSIE 6.0 and Netscape 6.0 had the same problem.
