June 28, 2012You should take a look at [url=http://www.prometheus-movie.com/community/forums/topic/8733]this thread[/url] I made earlier today discussing just this.
BUT - since I know how frustrating it is, I'll tell you how to fix it. When on a thread and trying to post a reply, if after logging in, it apparently "logs you out" - do NOT, I repeat, do NOT try to log in again. Instead, REFRESH the page/thread you are currently on, and your browser should reset the appropriate session with your account.
The problem is caused because the browser is looking for an old session it has saved in your cookies that is not existent since a recent update I made to the site. So, refreshing the page which has supposedly "logged you out" - will force the browser to reset that session with the correct, existing one.
Trying to log in again could potentially confuse your browser further.
Hope this helps.
