I have an issue where the coupon is discounting the total and the order gets processed BUT it charges the discounted amount and then does another charge for the discount. So in essence no discount is give.
Also, in my admin if I look at the order I can see the discount amount but the total shows the amount without the discount.
I have version 1.9.3.4 and have recently switched to PHP 7. Could this possibly be the cause. Is php7 supported for CE 1.9.3.4?
I rolled back to php 5.6 and it is working fine. I will try Inchoo's php7 patch and see if that works for me. Once done I will post the results here in case it is helpful to anyone.
