… was called incorrectly – wp-includes/functions.php on line 4137

Hi Guys,

Trying to figure out why my webshop is called incorrect items, like billing_first_name and payment_method_title. It is only shown on the checkout/order-received page.

Becuase of billing_email was called incorrectly my customers don’t got the order mail any more. It had been like this since the last update of woocommerce
