Featured post not displaying properly

Hi, I manage https://davidbanther.com/ for a client and am having problems with how the featured post block is being displayed. We both have made visual changes to the site throughout the past day and something must have messed up along the way.

This is what the site used to look like: https://img46.imageshack.us/img46/2475/sitebefore.png You’ll notice the featured post isn’t what it used to be. Any idea how to fix this? I would really appreciate any advice. Thank you!
