Order confirmation mail contains attachment with no content by default. Now I have added another attachment (terms and conditions PDF) to order confirmation email, now it has two attachments.
How can I get rid of 0 byte attachment which is attached to all order confirmation email sent to users since installed Opencart 3.0.2.0? Controller file catalog/controller/mail/order.php did not contain any $mail->AddAttachment(...)
The 0 byte filename is constantly changing, for example: 1525019890
Thanks for helping!
