More information. Interestingly the message requiring the client to chose something from the field is being displayed, but the field is not shown because of the error.

I scratched my head and did it:

add_filter( 'woocommerce_package_rates', 'custom_shipping_rates', 100, 2 );
function custom_shipping_rates( $rates, $package ) {

    $shipping_class = 506; // HERE set the shipping class ID
    $found = false;
	$productsincart = count($package['contents']);
	
	foreach( $package['contents'] as $cart_item ) {
			
        if ($productsincart == 1 && $cart_item['data'];->get_shipping_class_id() == $shipping_class){
            $found = true;
        }	
    }

    if ( $found ) {
		return false; // If not found we exit
	}else {
		return $rates;
		
	}
}

Just don’t forget to assign the same shipping class to all variations of that product.

Unfortunately, no solution. Get rid if the jetpack i would say.

Nobody in polylang team is not interested into this issue?

Bump

Some workaround – lame one

$parent1 = $post->post_parent;
$parent2 = $wpdb->get_var(“SELECT post_parent FROM $wpdb->posts WHERE ID=$parent1”);

if (!($parent1==’318’||$parent2==’318′)){

include “news.php”;

} ?>

Anybody? Please!
