convict Posted December 16, 2006 Share Posted December 16, 2006 Such behaviour is because of OLD basket order id. If payment is NOT sucessful OR payment is sucessful but no redirection to store Order status remains Pending and basket is not emty. Customer MUST empty the basket not delete products from previous order because of old order id relaed to the previous order. If payment is successfull and customer is redirected to store Order status becomes Processing and basket is empty by default. Quote Link to comment Share on other sites More sharing options...
