I have a very basic wordpress and jigoshop install, from fresh I have the latest version of jigoshop and wordpress and have applied a very basic theme just to try and make them work (I am aware it is a mess but this is not the theme I will be using on the site, its just a very basic one I have put together), with 2012/13/14 applied Jigoshop works however even with the most basic of custom themes applied jigoshop seems to be missing its jQuery functionality.
I know I am going to get alot of people saying additional jQuery library calls or disable your plugins but I only have jigoshop active, NOTHING else not even Hello Dolly, and the theme you can see is extremely simple and is making no jquery calls at all, at the minute its really quite stripped back just so I can see what is going on.
Here is a link to the test site with test theme.
Obviously you may want to add to basket and checkout to see the bulk of the issues.
Any help would be greatly appreciated.
