Admin, Why is forum not allowing me to log in?

[xs650shawn]

When I tried to log in this morning, got the "you must register to log in" screen. Went through the process to change my password. Site logs me in after that. But upon leaving the site, I came back later, tried to log in, and checked the "remember me" box, wouldn't log me in. Again, the registration page came up. I have reset my password 4 times today, each time resulting in the "thank you for updating your profile" response, and logging me in, only to have to do it again when I leave the site. Why is this happening?
