timmer81 Posted December 17, 2009 Posted December 17, 2009 Hi there After searching the forums I couldnt find a simple straight forward answer. My paypal standard module is in sandbox mode, i have made several test payments but keep getting error message 'This Invoice has Already been Paid' Please can someone help me correct this issue I am new to oscom so be gentle. Many thanks Tim Quote
Jack_mcs Posted December 17, 2009 Posted December 17, 2009 (edited) There are many posts regarding this question but a quick fix is to complete the order with the Check/Money Order module to clear the order number.

Hi, Thanks for your reply. I made a fake order using the check/money order and then did one using paypal but still have the same problem. Quote
