title: Facebook Comment Plugin not working
body: <p>I have configured Facebook comment in website. </p>
  
  <pre><code>&lt;script&gt;
  
    window.fbAsyncInit = function() {
      FB.init({appId: '****************', status: true, cookie: true,
               xfbml: true});
    };
    (function() {
      var e = document.createElement('script'); e.async = true;
      e.src = document.location.protocol +
        '//connect.facebook.net/en_US/all.js';
      document.getElementById('fb-root').appendChild(e);
    }());
  &lt;/script&gt;
  
  
      &lt;div id="fb-root"&gt;&lt;/div&gt;
  
  
  &lt;div class="fb-comment"&gt;&lt;fb:comments href="http://XX.YY.ZZ/website" num_posts="8" width="610"&gt;&lt;/fb:comments&gt;/div&gt;
  </code></pre>
  
  <p>Whenever someone login and comment, they got error </p>
  
  <p><strong>Sorry, this feature isn't available right now</strong>.</p>
  
  <p>Please let me know if it is because I have used IP address rather domain name, or there are settings in Facebook app for comment or anything else.</p>
