Prestashop // add to basket error //Need quick fix

Hi We have a problem in one of our clients Prestashop and all our freelancers are working on other projects, so we need help. When adding products to the basket an error makes it impossible to continue shopping. I have added a screen dump of the error. Only bid on this if you can take action on it today. If you provide good service and show you are a real pro, then we will consider using you for other projects on this client. When you bid, then please call me Bob - that way i know you have read my description. If you don't do that, then I will not take you into account. Best regards Jens
