Blogs MU login won't work unless I go to bottom of the page

I am not really sure why it does this but when you click on log in in the top right of the template it brings up a blank page and asks to add widgets. In the address bar the site is you need to create a log in page. http://friendzeron.com/you-need-to-create-login-page-in-page/ Is this something I can do in the wp-admin section or does it require coding or what. Another issue I am having is when users sign up to my site they can't create blogs. Only the admin can. I have WPMU and buddypress installed. Do I need to disable buddypress to make that work. I am trying to make a social networking site with blogging.
