I notice a very odd behaviour on the template.
When I try to edit a module from frontend everything seems working but when I try to open one of the subsections (basic, your slides, interface ... etc) the div slides correctly but unfortunatly after few seconds the page refresh closing the editor.
Otherwise if I try to open the one of the subsections after saving the changes I get an error
"Fatal error: Call to a member function getFieldset() on a non-object in /var/www/web3/html/main/components/com_config/view/config/tmpl/default_site.php on line 15"
Everything is fine if I edit modules from backend
I'm using joomla 3.4
