Michael - I see that you fixed this for Will. I have the same issue. Client is pissed. We were getting New order admin notification emails but now we are not. At a recommendation I instaled WP-MAIL-SMTP plugin and had it set to SMTP but nothing was working so I just went back to PHP mail().
If I send you user credentials to support@.... can you take a look and make sure I have it all set up properly and get it working again?
I believe customer is getting emails but we are not when an order is purchased. We get the Paypal email, not the Jigoshop email.
So perhaps run a test order and we will see if we get the New order admin notification emails.
Let me know and I will set up credentials.
Thanks.
