Hi,
This is a generic error message. It happens when the server didn't return any error message when trying to add a product to the cart from the browser.
Similarly, if I try to directly access the add to cart URL with my browser on your website ( for example:
roadtransportimages.com/component/hikash...tecart/add-1/cid-674
), I don't get an error message.
This is strange, because HikaShop always adds an error message when something is wrong. And the error message is different for each kind of problem so that the customer knows what's wrong, and admins can more easily diagnose the problem.
However, not only HikaShop can refuse an add to cart. Thanks to our cart API (
www.hikashop.com/support/documentation/6...umentation.html#cart
) any plugin can refuse the add to cart. In this case, it is up to the plugin to add the error message since HikaShop doesn't know why the plugin is refusing the add to cart. When we develop such plugins on our end, we make sure to do it. But it's possible that your client has installed a third party plugin or extension which cancels the add to cart without providing an error message.
So, my first question would be to ask what did your client do recently on his website before this stopped working. Did he add or update an extension ? Which one ? Maybe just this will be enough to find out what the problem is. At least, it will probably help in understanding what the problem is.
While a backend access would be great, we would probably also need a FTP access in order to do some debugging, because otherwise it is really hard to find which plugin generates the problem.
