My blog post titles do not show up

I'm using the Janela theme. I used a code to get rid of the page titles, but it may have also gotten rid of the post titles. Can't figure out how to make it reappear. I'd be okay with keeping page titles if it means fixing this.

My site is giving20percent.com.

Any advice?

Hi!
As I can see you have brought all the titles back, don't you?
