Reply To: Coupon notification error after plugin installation

[Torben]

My site is at https://tickets.universe.dk/

please try and purchase a ticket for 9 April 2017 ( https://tickets.universe.dk/billetkalender/ ) and apply the coupon code ‘sonderjyske’ at checkout. (PS. the coupon is not valid for that day!)
This will showcase the issue with the quick clearing of coupon notification messages.
