Hello,
I have a problem with Addon Coupon Extra Fields add-on.
When I proceed to it and attempting to create a new coupon, I get the following warning:
"Please enter license key (Addon Coupon Extra Fields)"
But I have a valid license. It seems something went wrong.
All details were been sent to you via PM.
Please help.
