Product size problem in cart

[afrajag]

Hi,

I got a strange error: sometimes when a customer put a product with a certain size in the cart (eg. a shoe with size 44), when he does do the checkout in the cart there is a wrong size (eg. same shoe as above but with a size 42).

 

It occur in a random way, but many customers is writing me with this problem.

 

I can't understand where the problem is: the only thing that I notice is that prestashop always put the same product but with the smallest size (eg. for the shoes) in the cart.

 

I have Prestashop 1.6.1.5.

 

Any ideas ? solution ?

 

Thanks,

Fabrizio

Perhaps your customers are clicking the "Add to cart" button before the JavaScript has fully loaded? That might cause the default combination to be added instead of the selected one. You could try making the "Add to cart" button disabled by default and then enable it once the JavaScript has fully loaded. I can't be sure that's the cause of your problem, but you can try.
