Hi
I see a JS error :

TypeError: JSNUtils.setInnerLayout is not a function
porty.org.uk/templates/jsn_epic_pro/js/jsn_template.js
Line 25

try to fix this, but if it worked before the best would be to know what you have made

The problem arose after I updated to the latest version of the JSN Epic Pro template I use. Does this help?

Uncaught TypeError: Object #<Object> has no method 'setInnerLayout' jsn_template.js:25

this caused by your template, I can't help you. You must fix this
