I have the newest version of Quick2Cart, brand new install. I'm curious: Does the coupon button not work in a multi-vendor environment? I logged in as a regular user (test account) and opened a store, added products, and when I go to coupons I see a green button for "Add Coupon". I click on it and... Nothing. Nothing happens at all.
I activated Bootstrap. I de-activated bootstrap. (In Quick2Cart options). Same result. Nothing happens.
So, Did I miss something? Can users create coupons in a multi-vendor setup?
