Attached Invoice not send to admin

Hi,

Check that you don't have any extra space before or after the email address and that the email address is valid.
Check the spam folder of that email address.
Then, go in the menu Customers>Emails history and open the email with the PDF attached. In it, you should see the email address provided that the attach invoice plugin's order is lower than the HikaShop email history plugin in the Joomla plugins manager (so that the attach invoice plugin adding the PDF is done before the email is stored in the history by the other plugin.

Also, a simple alternative you can try is to edit the email via the menu System>Emails and add the email address in the "bcc" field there. It will do the same thing but in a different way as it's directly HikaShop which will add the email address as bcc, not the plugin.

Hi,

You say that the admin does not get the PDF. But does that mean that the admin still receives the email, just without the attachement ?
Did you try adding your email address in the BCC field of the order status notification email via the menu System>Emails ? does it work ?

Hi,

It's not possible that you get the email without the PDF.
Either you get the copy of the email to the customer with the PDF, or you don't get that email at all.
Please beware that you don't mistaken the order admin notification email which is sent to the merchant when the order is created, or the payment notification email which is sent to the merchant when the order is confirmed, with the order status notification which is sent to the customer when the order is confirmed and which is the one which gets the PDF attached to it.

If you don't get the copy of the email even with the BCC option in the System>Emails menu, then it's not a problem in HikaShop or the PDF plugin. The issue is with your email server or the PHPMailer library which doesn't support the BCC feature of emails.
It's a common issue based on how you send the emails on your server (SMTP, mail, on linux, or on windows):

And, yes, the "send a copy to" setting of the plugin is supposed to do the same thing as the BCC setting of the email in the menu System>Emails. It's just that the BCC setting didn't exist when the "send a copy to" setting was added to the plugin and thus you have two ways to set it up.
