Having issues with Pro Site

I am using ProSite on Wordpress. Every time a user or myself create a website/blog on the front-end of my website and try to edit the theme, change themes, add page, or add post..etc, it says "You attempted to access the "My website name" dashboard, but you do not currently have privileges on this site...etc Whenever I visit the page created by the user or myslef, the page tab says " Page Not Found" Can someone please help me fix these issues? I just want the users to be able to signup for my site and edit their website/blog.
