title: Facebook like button appear in random way
body: <p>I added XFBML facebook like button plugin on my site for activity entities, but button shows only for one of them in random order. Code looks like:</p>
  
  <pre><code>&lt;body&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;fb:like href="&lt;%=activiy1_url%&gt;" send="false" layout="button_count" width="100" show_faces="false" font="verdana"&gt;&lt;/fb:like&gt;
  ...
  &lt;fb:like href="&lt;%=activiy2_url%&gt;" send="false" layout="button_count" width="100" show_faces="false" font="verdana"&gt;&lt;/fb:like&gt;
  ...
  &lt;fb:like href="&lt;%=activiy3_url%&gt;" send="false" layout="button_count" width="100" show_faces="false" font="verdana"&gt;&lt;/fb:like&gt;
  ...
  &lt;/body&gt;
  </code></pre>
  
  <p>Open Graph tags are present on the page. The same problem for iFrame button. What can be the reason ?</p>
