Embedding not working

I was editing a page on my site today, and once I completed the edit, updated and viewed the page, an embed from Vimeo stopped working (the embed wasn’t what I was editing, so I didn’t change anything related to it).

Here is the page in question: http://www.publicworksinc.org/lw/

I’ve tried re-embedding several times and checked that there’s nothing hidden in the HTML that might mess with it. Embeds work just fine on other pages of the site. I’m stumped, so any insights would be great!
