 * Hi,
 * The mentioned lines calls WooCommerce:
    `WC()->cart->needs_shipping_address()`
 * I can not tell you why but for some reason, WooCommerce’s cart reporting is not
   working. Does this also happen if you do not have any plugin activated but WooCommerce
   +GTM4WP?

 * Hi,
 * It hard to replicate the issue.

 * Temporary solution, I will check the condition is_null(WC()->cart)

 * etc billing fields unset?
