It seems that after a recent upgrade of WordPress and its Plugins, the PDFs have stopped sending to the store admin. I can preview the PDF in the back-end, so the generation itself is working fine, but the PDF isn’t on the transaction report e-mail (yes that option is also activated) nor available in the order history as it used to be. I have looked in the debug.log and I cant find any errors there.
Only if I set it so that the PDF should be send with the order confirmation, does it send the PDF to both the customer and the store admin. This must not happen though as we need to review the order first.
Or if I set it to send on successful payment, then it also sends it but ONLY to the customer NOT the store admin, upon completing the Paypal payment or when the order is set to paid manually in the order history.
