Login Failure

Hey, I love this script, and am currently running two working versions of it at the address http://www.whtieantics.net.  I loved it so much I was going to use it as part of my portfolio of the work I have done. (Was going to show pictures I have created)  However I have several problems with installing this one and after digging around on the forums a while have found the answers to all but this last problem.  

I can't log in.  When I type in the username and password, it goes back to the main page where I started, but I am not logged in, however it shows me as logged in at the bottom where it mentions who else is here..  Did I miss a post about this??  Or have I done something drasticly wrong?

Problem corrected.  I don't know what it was, however I just let it sit overnight.  This morning it worked fine.  This is rather odd since my other set's of this script were working fine last night, and yes I cleared history and all yesterday.  Anyone know what the difference between last night and today was?

just some "wild" guesses:
server problem that didnt accept correctly sessions?
cookies or/and session in your browser got corrupted - sometime its good idea clear your internet cache and cookies.
