Facebook Comments' hook not working on some themes?

Hi there,

In my Ultimate Facebook settings, I did turn on the the comments as shown.

However, on my blog, it is not showing

I have changed theme to test it out, and it did appear on Twenty Eleven.

Can you kindly help to look at my theme and see where it goes wrong? I'm using Cutline from the 133 pack. Or you can visit my blog to check it out. Here's a link to a direct article: http://flme.ch/hfj

Thanks for your help!
