Still Unable to upgrade
Using Jamroom
If your using the latest Nova skin, the JS for those tabs has been moved out of the jrNova.js file and into the templates. So this code:
<script type="text/javascript">
$(document).ready(function(){
jrSkinInit();
});
</script>
is no longer needed and could cause issues. Instead the actual javascript for each page has been added directly into the templates for that particular page. For example, the index.tpl now has this instead:
<script type="text/javascript">
$(document).ready(function(){
jrLoad('#sm',core_system_url +'/index_artists');
jrLoad('#top_artists',core_system_url +'/top_artists');
jrLoad('#top_songs',core_system_url +'/top_songs');
jrSetActive('#default');
});
</script>
Hope this helps!
