Coupon code not working on checkout page

Does that coupon exist with that exact, case sensitive name? And is it valid i.e. has an amount etc.

I found problem. I use qTranslate-X with Woocommerce and need add other language code.

Hi bojan, how you add other language code?
i’ve the same problem…
Thank you

Yes, i fix the problem. You need add coupon code for all language.

If you add only for 1 language, Coupon code can’t work.
