When the screen width is made narrow enough to make the menu switch to the mobile version or the site is viewed on a mobile device the the menu no longer functions if the Joomla Caching is enabled
With Joomla Caching turned on no mater what menu option is selected the website remains on the home page - Switch Joomla Caching off and it comes good again - Switch Joomla Caching on and the menu will work 2 or 3 times than stops.
I see this on both "Developer Box" and "Yougrids 1.04"
Ipswich - Yamanto Metal Traders
"Developer Box" Caching is off - Menu works on narrow screen width
Car and Truck Licences - Ipswich Prodrive
"Yougrids 1.04" Caching is on - Menu does not work on narrow screen width.
I have changed the Custom.CSS file on both sites
I have changed yjresponsive.js on ipswichprodrive.com.au function size_menu() and function resize() widths changed from 980 to 768
