Ok, I think this is it. Edit the file
sessions.php in the includes folder of 4images.
Find:
PHP Code:
($this->session_id = $this->read_cookie_data("sessionhash"))
and replace with:
PHP Code:
($this->session_id = $this->read_cookie_data("bbsessionhash"))
Now everything seems to work just fine. I have NOT tested this thoroughly so use at your own risk! Please let me know if it works or if there are any other problems.
