 * Hi, I realized that the “enable debug” mode was on and that’s why I was getting
   the error in the wordpress admin.
 * Question: Can I use Custom Fields to be included in the PDF invoice?
 * Thanks!!

 * Hi! Indeed, these errors are from another plugin: [https://wordpress.org/plugins/import-users-from-csv/](https://wordpress.org/plugins/import-users-from-csv/)
 * Yes custom fields can be included in the invoice, check the documentation here:
   [Displaying a custom field](http://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/displaying-a-custom-field/)
 * Hope that helps!

 * Thank you. I’ll try your suggestion. I have another issue: PDF Invoices are not
   being sent to Admin (Fulfillment) email. What do I need to do to make this work?
 * Thanks!!

 * I am also using WooCheckout Manager which allows for custom fields. Can that 
   be incorporated to your plugin?

 * Hi! WooCommerce has only one built-in admin email, which is the New Order email.
   You can attach the invoice to this email, but that’s not recommended practice
   because this will generate invoice numbers for all orders, including the ones
   that end up cancelled or failing.
    The [professional extension](https://wpovernight.com/downloads/woocommerce-pdf-invoices-packing-slips-professional/)
   offers an [additional email](http://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/configuring-the-order-notification-email/)
   that you can configure to be sent to a specific email address (or multiple) at
   a specific status. Alternatively, you could [add the admin as a BCC](https://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/receive-a-copy-of-each-invoice-sent-by-email/)
   to one of the other WC emails.
 * Fields for the WooCommerce Checkout Manager are no different from other custom
   fields, so the [same guide](http://docs.wpovernight.com/woocommerce-pdf-invoices-packing-slips/displaying-a-custom-field/)
   I linked in the post above applies here.
 * Hope that helps!
