PDF invoice not attached to admin e-mail

Hi,

Is the order status changed to "confirmed" in the order after the payment ?
And what do you have under the "invoice" column of the System>Order statuses menu ?
I suspect that the issue is that the invoice is not available yet for the order when the email you're looking at is generated.

Hi,

Yes, the invoice is only added to the order status notification sent to the customer.
I didn't see you were asking about the email you receive as admin.
What you can do then is disable the "payment notification" email via the System>Emails menu, and instead add your email address in the bcc field of the "order status notification" email. That way, you'll get a copy of the email received by the customer, with the invoice, instead of the payment notification.

Hi,

I did a test with the access you provided with my email address entered in the "Send a copy to" setting of the plugin and I did get a copy of the email when the order was confirmed (it took a few minutes before arriving).
So it looks like it's working fine as far as I can see. If that other email address doesn't receive the copy of the email then I can only think that there is a problem with that email address (for example, the email server rejecting the email as a spam)
