So I've started using a child theme (Twenty Eleven).
But it seems that it's broken.
As you can see on my site: http://www.geimaku.com/2012/04/20/hello-world/ the side-bar is placed above my site's nav-links for some reason. And the side-bar doesn't disappear when you go to another page -- In Twenty Eleven, the side-bar appears on the home page.
Anyone know what's wrong? And how I can fix it?
