No invoice with email

Wait, I forgot to enable in the settings of Woocommerce to send letters)

!

Still not working as it should. Invoice comes only in case if the client is authorized!
What to do?

Are you talking about the email not arriving? Or is the email arriving without attachment?

Please check your PHP error logs. If you have any functions in the email that are fetching user data and the customer is not registered, this may break.

To narrow down the problem it also helps if you turn off all custom snippets related to PDF invoices in your functions.php, and switch to the simple template. If that fixes it, you know your issue is in the customizations.

Another possible cause is a plugin conflict.

Hope that helps!

No email, no pdf invoices to user.
Where check PHP error logs? How?
Template is Simple – I don’t change anything

This message was added in version 3.0.

If the email is not sent, and there are no errors in the logs referring to PDF Invoices (I don’t see any in the logs you posted), then it’s a WooCommerce issue. It may be the WC Cloud Payments plugin as it doesn’t appear to be compatible with WC3.0.

I think I understand. I use plugin Gravity forms for pricing of the product. But the Email field does not make the data in the value billing_email, so Woocommerce knows where to send the letter. But what to do – I don’t know.

I suggest contacting Gravity forms about this. Good luck!

All easier. On checkout page I have added an Email field
Thanks!
