Listings are not showing on listing page

I cannot see the listings on my listing page, however, I can see it when I go to the “my listings” page.

Here is the url to my listing page and to the website:

I think I have determined it is a theme issue. When I switch to the twenty eleven theme the listings show. I cannot switch themes as the site is already developed I would like to get this working on this theme.

I am well versed at theme/plugin modification, php, html, and css. I just am not sure where to start debugging.

Please help..
