Hello,
One of our customers reported getting the following line of code at checkout:
Notice: get_used_coupons is deprecated since version 3.7! Use WC_Abstract_Order::get_coupon_codes instead.
The directory it refers to is in private content. I updated to the latest Classico template but the site crashed so had to revert back to version 2.4 (child). How can we hide the error or can you correct it in functions.php?
