## WordPress Multisite Network
By default, editing the Ping Services for a WordPress Multisite network site is disabled. This can be re-enabled with a plugin such as the [Activate Update Services](https://wordpress.org/plugins/activate-update-services/) plugin.

By default, editing the Ping Services field is disabled for individual sites in a WordPress Multisite network. To restore this option, you can add a small custom plugin or must-use plugin with the following code:

```
add_action( 'init', function() {
if ( is_multisite() ) {
// Allow the Update Services configuration screen to appear.
add_filter( 'enable_update_services_configuration', '__return_true', 11 );

// Whitelist the 'ping_sites' option so changes can be saved to the database.
add_filter( 'whitelist_options', function( $options ) {
$options['writing'][] = 'ping_sites';
return $options;
}, 11 );
}
} );
```
