title: Facebook send button disappeared after sometime
body: <p>I just added a Facebook Send plugin on my site. Everything worked perfect but after sometimes the Facebook send button disappeared. When page is reloaded, send button appear again.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;div id="fb-root"&gt;&lt;/div&gt;
  &lt;div class="fb-send" data-href="http://www.google.com" &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&amp;appId=519408*********";
      fjs.parentNode.insertBefore(js, fjs);
  }(document, 'script', 'facebook-jssdk'));
  
  &lt;/script&gt;
  </code></pre>
  
  <p>There is one more problem with the Facebook Send plugin,the auto generated <code>&lt;ifrme&gt;</code> tags height and width are 1000px. If I inspect the elements this code will appear.</p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;iframe name="f3ff0f29fc" width="1000px" height="1000px" frameborder="0"  allowtransparency="true" scrolling="no" title="fb:send Facebook Social Plugin" src="" style="border: none; visibility: visible; width: 0px; height: 0px;"&gt;&lt;/iframe&gt;
  </code></pre>
