hello, i have a problem with a code from facebook (likebox):

Code:
<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/pl_PL/all.js#xfbml=1";
  fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-like-box" data-href="https://www.facebook.com/sweetplayltd" data-height="300" data-colorscheme="light" data-show-faces="true" data-header="true" data-stream="false" data-show-border="true"></div>
LikeBox FanPage is showing on Firefox and Chrome, but on Internet Explorer i see nothing and on my Xperia phone too ;/ donít know where is the problem. Position for the LikeBox is only for test. i put this code in System->configuration->design->footer->Miscellaneous HTML, but i tried to make fanbox with JS too, put the code directly in head and body and always the same problem with IE.

here is the destination site: http://sweet-play.com (likebox is in footer).
please help
