why is the menu and home page content not showing up?

If i set homepage to a static page (and even if it isn’t) you don’t see what you should


but if you go here: http://www.mobileappbizinabox.net/demo1/about

then you see stuff correct if you click on the home tab (which is set as a static page) it does something weird.

how can I fix this? as it does it for any demo site setup I make same issue.
