Hey!
I'm rather new to phpBB but I've discovered the same problem. I recently installed the latest phpbb version when I launched a fansite for actor Ewan McGregor. But for some reason it won't let me login anymore. Despite the fact that I removed all cookies and deleted the files from my TEMPORARY INTERNET FILES + erasing site history I can't login, even if I tre several times. But instantly, after I've tried to login it claims I'm online and logged in (I can see my nickname in "Registered Users:") athough I'm not! 8O I don't recall making any recent changes to the board except for allowing guests to post and reply to existing topics.
I use Windows 2000 and IE 6 SP 1. And the weird thing is that when I tried to log in at school where we use Windows 98, it worked! 8O But instantly when I tried to log in at home, it didn't work... -- wait, whoa! It logged me in (after the 4th time of trying)! Woo! But, I'm still wondering about this coz this isn't normal, right?
