Hi....
So my system is using paypal standard and banktransfer as thier payment method.
I have some custom functions such as discount coupon and member credit feature.. Some requires to update/deduct the credit balance and coupon status after being applied through successful transactions. However, my banktransfer (checkout_process.php) works fine without any issue (can update all the credit and coupon status), wheareas my paypal standard seems cannot update the tables..
Currently I placed my code under before_process, that's mean I should place under after_process?
