title: Facebook like box : ''Page could not be reached" Error
body: <p>I created a fb like-box at <a href="https://developers.facebook.com/docs/reference/plugins/like-box/" rel="nofollow noreferrer">https://developers.facebook.com/docs/reference/plugins/like-box/</a> </p>
  
  <p>But when I tried to like it, it gives the error as in the attached image. When I clicked on <em>error</em> link, it says <code>The page at https://www.facebook.com/phonekade could not be reached.</code></p>
  
  <p>This works fine with my other fb pages. So I can't understand what the problem is. Can anybody help me here? Thanks in advance. </p>
