Hi,
First off: well done team on VM3 - great job.
I had a problem with my add to cart button not adding anything to the cart when the Cart Module was published - neither in the module or the cart page.
I was getting a jQuery error, jQuery(...).live is not a function, on line 24 of /modules/mod_virtuemart_cart/mod_virtuemart_cart.php
My template uses jQuery 1.9.1
The code in question is:
jQuery("body").live("updateVirtueMartCartModule", function(e) {
the .live event handler was deprecated in jQuery 1.7 and removed in 1.9 (
http://api.jquery.com/live/)
In order to get this resolved it simply takes changing the .live to .on
jQuery("body").on("updateVirtueMartCartModule", function(e) {
and all works again......
Hope this helps someone.
