Hi Umberto,

In WordPress Multisite, the registration settings are typically controlled at the network level rather than for individual sites. This means that the Network Admin controls whether or not new users can register across the entire network. Unfortunately, by default, there’s no built-in way to activate or deactivate registration on individual sites independently from the network.

However, you can implement a solution with a custom plugin or a code snippet to enable registration control on individual sites.Approach: Use Custom Code (or a Plugin)

1. Restrict Registration per Site using a Plugin: There isn’t a built-in setting in WordPress Multisite to enable site-level registration controls, but you can either create a custom plugin or use a plugin like “WP Multisite User Registration” or “Multisite User Management”. These plugins provide additional control over registration on a per-site basis.Alternatively, you can add custom code to your theme’s functions.php file or a custom plugin.
2. Custom Code Solution:Add this code to the functions.php file of your theme (preferably in a custom plugin so it’s not lost if you change themes):

// Disable user registration for individual sites in a Multisite Network
function disable_site_registration() {
// Only run on individual sites
if ( !is_multisite() || is_network_admin() ) {
return;
}

// Check if registration is disabled for the network
if ( !is_user_logged_in() && !get_site_option( 'users_can_register' ) ) {
    wp_die( 'User registration is disabled on this site.' );
}

}
add_action(‘init’, ‘disable_site_registration’);

1. This will ensure that registration is controlled by the network settings, but will block registration on individual sites if the network-wide registration is disabled.
2. More Granular Control with Plugins: If you’d prefer a plugin solution, you can try these:
   • User Registration – WP Multisite: This plugin allows you to configure registration per site and provides better control over registration on a per-site basis.
   • Multisite User Management: This plugin provides additional controls for user roles and site-specific registration options.

How it works:

• The above code ensures that if network registration is disabled, it will prevent users from registering on the individual site level as well.
• By using the get_site_option( 'users_can_register' ), you check if user registration is enabled at the network level.
• If you want specific sites to allow registration, you could further modify the logic by adding conditions to check for certain sites (using get_current_blog_id()), or by creating a custom option that controls registration per site.
