Error code after applying gift certificate balance

Hello Seyi,

My gift certificate balance working perfectly, but every time I applied my gift certificate balance value in the cart, a error message "Gift Certificate: Coupon code not found or expired." appeared.

Although the checkout amount is correctly reduce by the balance, but the error message still can confused customers.

Do you know how can I solve this? Thank you.

Hi, from the image, seems like you are using a one page checkout.  If you disable it, do you get the same issue?  If not upgrading the onepage might fix the problem.
