[FIX] nodes[i].parentNode.href is undefined

Disqus is isn’t checking to see if the parent node has an href attribute before it tries to utilize it. To correct this issue, open /wp-content/plugins/disqus-comment-system/media/js/count.js. The code should read as follows.

var disqus_shortname = countVars.disqusShortname;
(function () {
    var nodes = document.getElementsByTagName('span');
    for (var i = 0, url; i < nodes.length; i++) {
        if (nodes[i].className.indexOf('dsq-postid') != -1) {
            nodes[i].parentNode.setAttribute('data-disqus-identifier', nodes[i].getAttribute('data-dsqidentifier'));
			if (nodes[i].parentNode.href) {
				url = nodes[i].parentNode.href.split('#', 1);
				if (url.length == 1) { url = url[0]; }
				else { url = url[1]; }
				nodes[i].parentNode.href = url + '#disqus_thread';
			}
        }
    }
    var s = document.createElement('script'); s.async = true;
    s.type = 'text/javascript';
    s.src = '//' + disqus_shortname + '.disqus.com/count.js';
    (document.getElementsByTagName('HEAD')[0] || document.getElementsByTagName('BODY')[0]).appendChild(s);
}());

Disqus plugin team: Please fix this, for it is broken. ?? This issue has gone unresolved for almost a year now.
