Page Content Disappeared! But still there in dashboard edit...

One of our pages shows up with only the title, and all the other content is missing. But when I go to edit the page, the content is all still there. Even the visual editor shows what the page normally looks like. But the page itself is blank.--> http://sierraclubcalifornia.org/news/

I've tried making a new page with the same content, which also ends up blank. I've tried turning off all my widgets, and un-doing the changes I made to the index.php; but that did not make a difference either. I have no idea why this would have happened--I can't think of any changes made to the page between when it was working to when it stopped working (although, I am not the only one that works on the site, so someone else certainly could have done something...).

I'm posting the html here in the desperate hopes that someone may know what's wrong.
