title: Facebook comments plugin - same comments on every page
body: <p>Facebook comments on my website work well except the fact when someone comments on one article that same comment shows up on every article on the website. Obviously, I don't want that. What I did is basically copy and paste code offered on developers.facebook.com:</p>
  
  <pre><code>      `&lt;div id="fb-root"&gt;&lt;/div&gt;
        &lt;script&gt;(function(d, s, id) {
        var js, fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) return;
        js = d.createElement(s); js.id = id;
        js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";
        fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));&lt;/script&gt;`
  
  
       `&lt;div class="fb-comments" data-href="http://example.com" data-num-posts="2" data-                                      width="470"&gt;&lt;/div&gt;`
  </code></pre>
  
  <p>What did I do wrong? I would appreciate any help.</p>
