Excerpts aren't showing

Hi,

I had this all setup on a site and it was working beautifully. Then I moved it out of development and now the excerpts aren’t showing. I have compared settings in both sites side by side and everything looks exactly the same. Do you have any idea why it’s not working on the withmefit.com site?
And yes, I have the box ticked to show excerpts.

Works: withmefit.rumspeed.com
Doesn’t work: withmefit.com

Thanks!
