title: When posting a link on Facebook, the title and thumbnail are missing
body: <p>When I try to post a link from my blog on Facebook, either directly by copy/pasting the url or using a Wordpress plugin, Facebook "refuses" to pick up the title and the thumbnail picture of the post.</p>
  
  <p>I've had this problem from time to time for a couple of months, but for the past 3 days I haven't been able to post a single post from my blog to Facebook and I can't see what would be the problem.</p>
  
  <p>This is how it should work:</p>

  <p>Has anyone experienced something like this or has any idea of why this isn't working for me? I can post other links on Facebook, it's just my blog that's screwing with me :o</p>
