HiĀ Hassan!
Thanks for getting in touch. Let me help you with that.
If you placed the email.php template file I provided insideĀ [your-theme]/tribe-events/tickets/email.php it should not get overwritten when updating our plugins.
Could you please confirm that’s where you placed the template override?
Regarding the ticket image and QR code missing, I’m not sure exactly where you see this difference. I tried reproducing this myself, but I can see the QR code showing fine in both the email and PDF ticket. Do you experience any difference?
Let me know about it.
Thanks,
Victor
