Blocco Theme

Hey!

I have a problem. Got this “Blocco” theme, very nice and all, but main container is acting not like it supposed to. On every post section it should look like this but insted for me it looks like THIS. As You can see, the white container just stops and the rest of bottom part does not look good.

Tried to change some things in style.css file, couldn’t find the solution ?? So i really hope someone here can help me.
