I'm attempting to create a discount code for my checkout and have no problem creating it and it seems to work perfectly when I'm logged in as admin. When acting as a customer trying to input a code into the box, there is no cursor or font visible and the "apply" button is white/transparent so it doesn't look like anything happens. Even though there is no font, I've tried typing in the code (you can't see it) and click on what appears to be a blank apply button and it works. How can I change it to show what is being typed?
