Answer 1

This error must be generated through some third party module on your store. In order to identify the module you need to observe the ajax request (Sent on 'Add to Cart' click), after enabling error debugging.

FYI, to enable error debugging you can follow the steps below.

• open file: config/defines.inc.php (using FTP or hosting control panel)

• change false-->true:

define('_PS_MODE_DEV_', false);

define('_PS_MODE_DEV_', true);
