After Upgrade - Previous Coupons Say Invalid When Used

After I upgraded to the latest version, the coupons that I already had now say "This Discount Code Is Not Valid" when trying to use.

Any suggestions where to start looking?

I am using RedShop with their latest version.

I did not have any issue using the AWO coupons before upgrading both RedShop and AWO.

I have also tested creating new coupons and they don't work either.

I think I have looked at the normal settings and they all look correct.

Coupons and vouchers created in RedShop do work.

I am open to any suggestion.

Hello,

Have you checked AwoCoupon->installation check? If you upgraded Redshop, the injections would be wiped out and have to be installed again.

You are an absolute godsend. I have been beating my head against the wall for about 5 days.

Thank you!
