Can't add product to existing order

[Tomas LT]

Hello.

 

I can't add product to existing order in BO.

 

Test with prestashop online demo. Same issue, but error code in my store is different:

 

Impossible to add the product to the cart.

textStatus: 'parsererror'
errorThrown: 'SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data'
responseText:
Fatal error

 

How to fix this?

 

Thanks.

Strange. The full message from live demo BO is:

Impossible to add the product to the cart.

textStatus: 'parsererror'
errorThrown: 'SyntaxError: JSON.parse: unexpected character at line 2 column 1 of the JSON data'
responseText:

Looks like you have development mode enabled, since you have a notice that is causing the AJAX to crash. You can either disable development mode or fix the notice by changing line 2153 of controllers/AdminOrdersController.php from:

        $refresh = false;

to:

        $refresh = false;
        $res = true;

This is a bug in PrestaShop that should be reported. Let me know if adding this line of code fixes your issue, then I'll submit a bug report.

 

A better solution may be to remove the $res variable altogether, since it doesn't appear to be used anywhere.

I am using prestashop 1.6.0.6 and I am receiving same error when I click "add to cart button". I did look for the file and the variables but there were no such variables.

here is the error that I am receiving:

 

"Impossible to add the product to the cart.

 

textStatus: 'parsererror'

errorThrown: 'SyntaxError: JSON.parse: unexpected character at line 1 column 1 of the JSON data'
