Prior to the patch, I was able to create promo codes within Magento without any problems. After the patch I am able to create new promo codes, but upon checkout they are "invalid". Old promo codes still work just fine, however if I make a change to an old promo code is now becomes invalid.
Has anyone experienced this? I'm not running any third party apps for promotions just the base Magento one.
Running Magento 1.8.1
New Coupon code: test
Old Coupon code: order10
I have the same problem.
I can auto generate codes but they never work. Anyone have any ideas on how to fix this?
