This PHP fatal error occurs when creating a new user account from the backend.

It also appears to occur when a user account is created via the WooCommerce Checkout Process

    private function extractMessage( $mail ) {
        if ( isset($mail['message']) ) {
            // usually the message is stored in the message field
            return $mail['message'];
        } elseif ( isset($mail['html']) ) {
            // for example Mandrill stores the message in the 'html' field (see gh-22)
            return $mail['html'];
        }
        throw new \Exception(self::ERROR_NO_FIELD);
    }

It appears to be the $mail[‘message’] and $mail[‘html’] both pass NULL triggering the function to through the error.
