I can see that. And now I can get to the main page too.
One problem I see right away... the link on the main page sends you to
www.site.com. All the links on your site are for just site.com. If you allow users to login to your site via both
http://www.yoursite.com and just yoursite.com., then you MUST have your cookie domain (vboptions > cookies > cookie domain) set to ".yoursite.com" (no quotes, but note the period at the beginning) or your users will have problems. Also, make sure to tell your users to click the Remember Me button when they login.
