Theme not displaying properly

I'm running a BuddyPress website. I've install the theme and activated it. Instead of displaying the theme nicely, it just shows like in the picture. It also doesn't work for "Business Portfolio", "Buddy Magazine", "Studio" and "Business Services".
How do I make it work? By the way, the default BuddyPress theme works and also Custom Community 1.8 by Themekraft
