Forum Do Not "remember Me"

When I sign in I always check the option to remember me, but when I return to the forum next day I always logged off. So, is it a bug, or how the "remember me" option is supposed to work?

It’s supposed to work. Do you have cookies enabled?

Yes, of course. Other sites sign me in automatically. Here is the cookies I see: PHPSESSID, coppa, itemMarking_forums_items, member_id, modtids, mqtids, pass_hash, session_id. Is this enough?

Should be.
