Help adding questions to EDU-Knows theme

This seems like it should be pretty obvious, but I’m stuck. I installed the Edu-Knows theme on a blog here: http://support.youronlinepractice.com/

However, even though I’ve made several posts and categories, nothing is showing up. You can see that they exist, like this one:

But they don’t show on the front page. What am I forgetting!?
