SOLVED: Dynamic update of a cart module doesn't work after update to VM 2.6.2

[borro]

Hello!

Thank you for VM!

I made upgrade to VirtueMart 2.6.1. Now quantity and cost of a products in a cart(at the top right corner) can not be updated dynamicly without page reload if you click Add-to-cart button(green button).
Could somebody take a look at site?

I've noticed that after click on add-to-cart button such mistake arises:

GET http://www.antiloppagold.ru/index.php?option=com_virtuemart&nosef=1&view=cart&task=viewJS&format=json&lang=ru&_=1400490778377 500 (Internal Server Error)

What does it mean?
Is there script versions conflict?

It seems like there is some bug with JSON processing
I have the same problem in VM 2.6.2

It works fine. Did you fix it? If so, how?

Borro, I think you are using a too recent jquery version. We had the same trouble writing for j3.

Use in FE/assets/js/vmprices.js at around line 14 this

Code Select Expand


jQuery.getJSON(window.vmSiteurl + 'index.php?option=com_virtuemart&nosef=1&view=productdetails&task=recalculate&virtuemart_product_id='+id+'&format=json' + window.vmLang, datas,

I'm using jquery 1.7.2. it's not a recent version I think.

I cann't understand what you suggest in a row above. Do i need to find the reason of mistake in this row?
I think something has changed in VM, because the link like

site.com/index.php?option=com_virtuemart&nosef=1&view=cart&task=viewJS&format=json&lang=ru&_=1400592190950

works fine and returns such answer in VM2.0.18a:

but the same link doesn't return anything in VM 2.6.2. So where should I begin my investigations? By which url does VM 2.6.2 return the same answer? Please help.
