google plus button asynchronous code is not loading on several wp 3.6 sites

Is there anybody having a same issue?

code is:
<script type=”text/javascript”>
(function() {
var po = document.createElement(‘script’); po.type = ‘text/javascript’; po.async = true;
po.src = ‘https://apis.google.com/js/plusone.js&#8217;;
var s = document.getElementsByTagName(‘script’)[0]; s.parentNode.insertBefore(po, s);
})();
</script>

And when I put old one, everything is fine:
<script type=”text/javascript” src=”https://apis.google.com/js/plusone.js”></script&gt;
<g:plusone></g:plusone>

I tryed on two wp theme:
“Twenty Twelve” nad “renegade” – same problem…
