Hi yellow, I really need your help!! i installed ssu 3.6.7. when ssu is turned on and someone purchases a product they get a error saying "There has been an error processing your credit card. Please try again." and the order does not show up in zen cart admin but their credit card is charged. i use quantum gateway as a payment gateway. when ssu is turned off everything works fine.
this is my hta.access file
