I have a problem which order confirmation mail sent twice. I debug the cron.php file and it works good. My ecommerce send well all kind of email automatically but order confirmation mail.
I realize that it's not from cron job and it seems like order information is dupicated in email queue based on database problem.
What do you think of that? I'm really freaking out for 1 week. And could you let me know the which php file manage the order information?
Thank you so much !
