Hello all ☺
I am facing a weird problem with my site http://www.vanillka.com that is using wordpress theme.
When posting an article on facebook, there's no thumbnail. But...what is weird:
The last post (http://vanillka.com/2012/11/28/amaranth-raw-balls/) has no thumbnail.
All other post have thumbnail when shared that is the featured image from the post.
BUT...some weeks ago, when posting on FB, I could choose a thumbnail from all the pictures in the article, including the featured image. And I want it back!
What can it be due to?! Help, SOS! PLS!
