Facebook plugin error does not count amount of comments

I used the Facebook plugin on my website, for the like, share, facepile and comments buttons.

Everything works, except for the comments counter in each post, all the codes are correct, I used this script in Portuguese that facebook provides:

<div id="fb-root"></div>
<script>(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/pt_BR/sdk.js#xfbml=1&appId=300497003454434&version=v2.0";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>

The strange thing is that if I use the English script, everything works, only the description of the buttons is in English:

<div id="fb-root"></div>
<script>(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'));
</script>

How do I for the English script to display the correct amount of comments?
