Try PortableFirefox first and see if the problem replicates.

By the way, I am using Firefox 2, not the original. I am downloading portable Firefox now though.

EDIT: On my first use, the problem affects the portable version as well. And yet again it only seems to affect the Techious forum. Nothing else.

Try including the www. when you have techious.com

No. lol

Doesn't work. I literally went from this page where I was logged in and entered in the forum address, and it shows me to not be logged in.

So you've tried using http://www.techious.com signing in and remembering, then closing all windows and it still doesnt work?

I'm convinced that an uninstall, followed by removing all program files and registry entries, then reinstalling is the quickest and most simple option. It would take less than 10 minutes and would be almost guaranteed to either resolve this issue or narrow the problem down to something more uncoincidental, such as the OS. Bloody Windows.

But seriously, if you want this problem sorting, then uninstall, remove all traces of Mozilla and Firefox, then reinstall using default settings.

Actually, I'm pretty sure Si is right. The cookie domain is http://www.techious.com NOT techious.com, so you have to go to http://www.techious.com log in and check the box that says remember me or whatever it is then always come to http://www.techious.com. It must have the www.

I just checked the admin control panel, and that is what it is set as, and that is what it will work as. I also tried going to the site without www. and it doesn't work.

Right, I've fixed it.

I'll type up more later. It was partly what si said, but the problem was complicated with my name changing.
Because there were two possible logins, it would not auto-log me in, after the name change.

Before that, it was what you said, that only http://www.techious.com will work.

Still, I'm glad it's fixed now. Thanks for the help.

Yeah, name change always does that, you just have to log again.

I thought the cookies work off sessionids and userids (ie 4c3.... and 6 in my case)

Dunno, but when I changed my name it got affected.
