Headings and Photos don't show

I’ve had a website up and running for a while now and all of a sudden I’ve got some issues with the pages (not posts). I hadn’t been doing any editing at all, and now the headings (H1, H2, H3) and the photos on these pages are no longer visible on the website. The are visible when I go to the edit and preview pages, but they don’t show up on live pages. Go to the website (http://www.ellipticalvstreadmill.us/) and go to the elliptical machine page. That page has H1, H2, H3 headers and a photo, but you won’t see any of them.

Any help will be greatly appreciated.

Thanks,
Mark
