This has been happening to me alot recently when i want to post something on the forums. I log in correctly and it has the profile,inbox etc. up the top of the page. But, then i go to make a post or change pages on the forum, I'm logged out again. The continual cycle of having to re-log repeatedly is annoying and I was wondering if it happens to anyone else.
I logged in and had the "remember me" button checked. Come back later and I was auto-logged out. Still no biggy. Just getting this out there to hopefully get rid of the bug!
