AppThemes Coupons unstable at the checkout with vantage
I've noticed that the checkout process using AppThemes Coupons is unstable and sometimes applying the discount incorrectly.
The user choose a plan, type the entire listing information, is redirected to the Order Summary and sometimes the discount is not applied or the fields are scrambled.
I've already noted at "wp
-admin -> Payments -> Orders" that the orders are being saved with price zero frequently.
