Fatal error when no zone set

I’ve set up zones and am using ‘Locations not covered by your other zones’ to cover everywhere else in the world. PHP throws a fatal error when using this catch-all fall-back, as the foreach loop is trying to parse an array that doesn’t exist.

On line 1576, the foreach loop tries to parse the $delivery_zones[$zone_id][‘zone_locations’] variable. The fix I’ve come up with is to wrap this as follows:

					if (!empty($delivery_zones[$zone_id]['zone_locations']) && is_array($delivery_zones[$zone_id]['zone_locations']) && count($delivery_zones[$zone_id]['zone_locations'])>0) {
						foreach ((array) $delivery_zones[$zone_id]['zone_locations'] as $zlocation ) {
							$zone_countries[] = $zlocation->code;
						}
					}

This skips the foreach loop if the default fallback ‘Locations not covered by your other zones’ group is used in WooCommerce.

I hope this helps others suffering the same problem and hope this code (or similar) is added to the plugin in due course to stop such fatal errors.
