When view your source HTML, there some code, but not in the right place
<script type="text/javascript">
var uvOptions = {};
(function() {
var uv = document.createElement('script'); uv.type = 'text/javascript'; uv.async = true;
uv.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'widget.uservoice.com/CG0rJQjo87CGtVE7iPRw.js';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(uv, s);
})();
and missing close tag ???
And jquery is call after K2 script
<script src="/media/k2/assets/js/k2.noconflict.js" type="text/javascript"></script>
<script src="/components/com_k2/js/k2.js" type="text/javascript"></script>
<script src="/media/system/js/mootools-more.js" type="text/javascript"></script>
<script src="http://www.socialit.no//plugins/system/jatypo/jatypo/assets/script.js" type="text/javascript"></script>
<script src="http://www.socialit.no//components/com_gcalendar/libraries/jquery/jquery.min.js" type="text/javascript"></script>
>> Cause error in K2.
