I found a javascript error says that “(index):747 Uncaught TypeError: Cannot read property ‘0’ of null”
So, I checked the source code of index page, it seems caused by the following javascript:
<script type="text/javascript">
jQuery(document).ready(function () {
jQuery('.menu a').click(function(){
var match = jQuery(this).attr('href').match(/#S+/);
ga('send', 'pageview', location.pathname + match[0]);
});
});
</script>
I’m not sure what is that, it’s not generated by the original theme. How about after remove it?
Thanks
