I'm not sure if this is the right place or not, but I thought i'd ask. I've been struggling for a couple weeks as my urls stopped posting the thumbnail when put up on my facebook page. This only happens for embedded videos. Photos are fine. I am using All in One SEO Pack 22.214.171.124 and Open Graph protocol 2.0.2. I have searched the forum and saw a few other posts with similar problems, but the solutions did not work for me.
I am getting a Parser Mismatched Metadata error from the facebook debug.
http://Www.truetravellers.org is my site.
If anyone has any ideas i'd greatly appreciate it.
Thanks for your help.
Let me know if a better description is needed and I will take a crack.
