I'm fairly new to this, so sorry if this is a simple question.

I'm trying to install the FB like box onto my website www.thehungryeurasian.com

However, when I try inserting the Javascript SDK:

<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/sdk.js#xfbml=1&version=v2.0;

  fjs.parentNode.insertBefore(js, fjs);

}(document, 'script', 'facebook-jssdk'));</script>

The following error comes up:

Error parsing XML, line 884, column 64:

The reference to entity version must end with the ';' delimiter.
