this is really strange… if i test any of my urls using https://developers.facebook.com/tools/debug/ , i will get the Provided og:image could not be downloaded or is not big enough. But when i click the Debug button again, it gets rectified and facebook will grab the correct image and the error disappears. i know it has nothing to do with your plugin now…
I am using Yoast WordPress SEO with Facebook Open Graph Meta Tags for WordPress.
my site is tvtv.ml
