I am still on WP2.7 and my thumbnails from my blog posts no longer show on Facebook when I share a link to the blog post address. Since my WP blog is used for my business, it is pretty critical that my images are displayed as thumbnails on Facebook.
This is a fairly new problem... maybe just in the last few weeks.
Would someone please offer some help for me so that my images again show as Facebook thumbnails like they used to?
Any help is much appreciated!!
