Shopping Cart Summary - Ajax Problem

[PlaneSticker]

Hi there,

 

RIght - I'm a bit miffed by this one! For some reason when clicking the quantity + and -, as well as the remove button, in the cart summary page there seems to be a few problems.

 

Pressing + doesn't update the page - it doesnt add any items.

 

Pressing - removes the product from the page, no matter how many of the quantity are meant to be there.

 

Pressing the remove icon, removes the product, but again - the totals don't change.

 

my website is planesticker.com

if you want to test the cart summary and see.

 

I use the default theme.

 

I've then replaced the shopping-cart.tpl and shopping-cart-product-line.tpl of my current with the default files - and oddly, the problem still exists! I've then replaced the css files and js folder with the default - but again, still not working!

 

I think I'm probably missing something obvious here - but for the life of me I can't seem to find it! I'm using the latest prestashop 1.6.1.24

 

Any ideas? Thanks in advance!
