title: Facebook showing page not found when sharing link
body: <p>I'm sharing content from a website and every time I paste the link into Facebook it says 'page not found'. </p>
  
  <p>Sometimes it works when I manually add the 'www.' in front of the URL in the address bar.</p>
  
  <p><strong>EXAMPLE</strong></p>
  
  <p><em><strong>Shows page not found:</em></strong></p>
  
  <p><a href="http://roundreviews.co.uk/reviews/speakers/native-union-monocle-speaker/" rel="noreferrer">http://roundreviews.co.uk/reviews/speakers/native-union-monocle-speaker/</a></p>
  
  <p><em><strong>Works when you manually place www. in front:</em></strong></p>

  <p>I honestly have no I idea why it's doing this, any thoughts on how it can be fixed on the web side?</p>
  
  <p><em><strong>Also...</em></strong></p>
  
  <p>I have tried with the link below with both the www. and without yet it doesn't work with either of them, this is all very strange. This is the only link I have tried and it doesn't work with both:</p>
