I setup the config details then it takes me back to the cp.cgi and I get login request. I don't get any edit boxes to type in a username or password. Does anyone have any idea's?

Please post the URL to your cp.cgi.

I wiped my cookies and it worked. I had installed a 6.0 beta1 on the same domain before and was upgrading to beta 7.9 but it works now.
