Hello,
I got the impression that you mix-up "serials" and "coupons".
HikaSerial generate serials ; these have the status and other stuff that you're talking about.
But if you really using a coupon generator ; it's not the serial that you should look (because they are useless), you must look at the generated coupons.
So please, as asked previously, perform the checks on your HikaShop coupons.
