All Embedded Media suddenly started showing up as text!

Help!

So yesterday after putting a post up I noticed all the links on my site turned to text, every single one dating back to the beginning!

We’re talking Soundcloud, Youtube, Vimeo etcetc

look at the following examples :

https://stackedrecords.net/2011/12/27/top-10-of-2011ss/
https://stackedrecords.net/2011/12/23/redlight-get-out-my-head-video/

its like a site wide setting triggered this change, I cant figure it out though after a few hours of troubleshooting.

Please help, this is very frustrating
