Reply To: Cart empty Coupon message not displaying

Actually, the message is displayed, but it’s white text on a white background because of the following css that is in your theme customizer:

.woocommerce #respond input#submit, .woocommerce-page #respond input#submit, .woocommerce #content input.button, .woocommerce-page #content input.button, .woocommerce-message, .woocommerce-error, .woocommerce-info {
    background: #ffffff!important;
}

That’s why you can’t see it!
