TECHNICAL ERROR: unable to save update quantity and others cart disfunctions

[jimisens]

Hello everybody

 

I'm new in this forum, so i hope i'm posting in the correct forum. 

 

I have several problems with the cart updates and adds in mi website: http://test.roulezpapilles.fr

I'm using Prestashop 1.6.0.8 and a custom theme.

I'm using custom javascript and other librairies. (Foundation tools, Jquery transit, Jquery slimScroll...)

And also a custom Jquery version 1.9.1. 

 

I search about this problem in Google, forums, etc.. and i can't found the solution. 

 

You can see the errors where : http://test.roulezpapilles.fr/index.php?id_category=6&controller=category

 

First problem (with ajax cart set too yes): 

 

The cart works correctly from the product page. I can add product to the cart and also remove the product from the sidebar (where is my module cart). 

 

But when i am in a category page -->  ex.: http://test.roulezpapilles.fr/index.php?id_category=6&controller=category

 

I have these errors: 

 

Impossible to add the product to the cart. 

textStatus: 'error'

errorThrown: "

responseText:

 

 

And from the cart in sidebar: 

 

ERROR: unable to delete the product

 

 

Second problem

 

in the shopping cart summary: 

 

TECHNICAL ERROR: unable to save update quantity

 

Details:

Error thrown: [object Object]

Text status: error

 

 

 

 

In my diferent search i found these thread:  

http://www.prestashop.com/forums/topic/322095-solved-technical-error-unable-to-save-update-quantity/

 

it's about the diference between Prestashop 1.5 and 1.6 and about the cart.php in the new version that is not in the root directory.

Like i'm working from a old theme. I think the problem can come from my theme.

What i need too do please??

 

Thank you
