Unable to add product

[colobosya]

Hello,
I have exception thrown from ajax-cart.js every time I try to add a product to a cart.
TECHNICAL ERROR: unable to add the product.

Details:
Error thrown: [object XMLHttpRequest]
Text status: parsererror

the product did not have any attributes to it.

Quick search on the forum showed that most people have fixed it by disabling AJAX.
Did AJAX work for anybody at all?
Is there any other way to fix it?
How do I disable AJAX?

I haven't encountered that error message since PrestaShop v1.1. I've never had any problems in PrestaShop v1.2.5 and v1.3.1. Make sure that you all the files in your theme are the ones from the default v1.3.1 theme. To disable AJAX, go to Modules > Categories block (in the Blocks section) > Configure and change "Dynamic" to X, then click Save.

This is caused by an invalid json file. It's likely that you have single quotes in a product name or description. Try changing line 13 in /modules/blockcart/blockcart-json.tpl to this:

"name": "{$product.name|html_entity_decode:2:"UTF-8"|replace:"singlequote":""|addslashes|truncate:15:"...":true}",

The code block above wouldn't display it properly so you have to change singlequote to '

Please.. The blockcart-json.tpl doesn't have this code! so i can't substitute any code
