Buddypress social theme open to anyone

I have the buddypress social theme installed. However I need to give open access to all viewers (logged in or not logged in) to browse thru the website. The first login page is fine but when I click on any links in the menu the top section does not move but the page info shows at the bottom of the front page.

How can allow anyone to just click on the links and go to that page instead of the issue I am facing as described above. I have spent hours trying to change the menu's etc but it just does not allow me to create an open site. I am not using any membership plugin.

Thanks
