I got a warning message on the checkout page.
Warning: Invalid argument supplied for foreach() in /wp-content/plugins/woocommerce-apg-weight-and-postcodestatecountry-shipping/apg-shipping.php on line 637
Plugin is working but I want to remove this warning message. Something weird, when I update the checkout page (f5), warning message goes.
I am using the lastest version of Woocommerce 2.1.2 and last version of WordPress.
