Simply123 Posted November 13, 2014 Share Posted November 13, 2014 Hi there, I use Prestashop for my online store, everything was working perfectly until yesterday. I am not an expert user on Prestashop, but have found it easy enough to do the installation and maintain the site - I do have a little help from a web developer, but he does not know Prestashop well. Most problems are resolved by googling and going through forums, but I am stuck on this one. I am still on version 1.5.6.1. My shoppers are not able to add products to their cart - it says that it is impossible to add products to the cart. It does however, still add the product to the cart, after another product is selected. I have read up on a few of the forum topics and see that most have to do with: - memory allocated, which we've checked and is fine - paypal and payment gateways - I do not use paypal - there was an mbstring error on the config settings page, which we changed, but the error remains. Please find a screenshot of the error attached. Can anyone assist please and let me know things I can check? Or if additional information is required to check. Thanks!!
