Magento has fixed an issue that prevented some Discover credit cards from validating properly. The issue was that certain Discover credit card number ranges were not recognized as being valid. As a result of the fix, all Discover cards should validate properly.
This fix applies to:
- Magento Enterprise Edition (EE) versions 184.108.40.206–220.127.116.11
- Magento Community Edition (CE) versions 18.104.22.168–22.214.171.124
