Hello,
For support on HikaSerial ; please use the HikaSerial section of the forum.
In order to send the e-ticket, the ordre must be confirmed by a payment plugin or in the order details in the backend.
If you confirm the ordre in the backend order listing, HikaSerial won't be able to send the image because the email is prepare before the order confirmation ; so before a serial is generated.
But for more details ; please open a new thread.
