title: Wordpress post thumb disappears after sharing on Facebook
body: <p>I share a articles from this blog on my FB page: <a href="http://what-is-your-story.co.za/blog/" rel="nofollow">http://what-is-your-story.co.za/blog/</a> - when it contains an image, it shows the image in the preview mode on facebook, but after I post the link, the image disappears. It just shows a white block where the image should be.
  When I share an article from the same blog with no image, it still shows a blank thumbnail block where an image would've been (although there is none).</p>
  
  <p>I've tested it with the Facebook Open Graph Object Debugger, and the link looks fine with the image showing up if the article has one and no image/thumb area when there isn't one. But still if I share the articles on Facebook, it shows a blank thumbnail area for all these articles.</p>
  
  <p>The same happens when someone else shares these posts as well.</p>
  
  <p>Some screenshots of what I see in FB Debugger and what is actually posted: <a href="http://i.stack.imgur.com/yTxX8.png" rel="nofollow">screenshots</a></p>
  
  <p>Website / blog built on: Wordpress V4.4.2 | Gantry 5 framework V5.2.10 with Hydrogen theme</p>
  
  <p>Any ideas on what causes this and how I can fix this?</p>
  
  <p>PS: Sharing to Google+ shows the images just fine. No problem there. It seems to just be Facebook.</p>
