I'm on version 2.8 and I can't get the discount code to save in the frontend.
I can save discount codes perfectly in the backend with exactly the same information, so I don't think I'm missing something there. However, when I press on Save & Close on the frontend, nothing happens. The Cancel button works though!
Interestingly, if I go to the discount code page in the frontend and click to create a new discount code, if I straight away click on Save & Close then the form does give a message "Name is required" so the button is kind of working!
