MainWP removed the White Label controls that hide plugin and update-related areas in child site admin.

​
What You’ll Learn

  • Which White Label behaviors were removed
  • How to apply similar behavior manually on child sites

​
What Was Removed

The removed behavior included:
  • Disabling plugin, theme, and core update checks and notices
  • Redirecting restricted admin pages such as update-core.php and plugins.php
  • Hiding plugin/update UI elements in WP Admin (for example, Plugins menu and update links)

​
Why It Was Removed

These controls required filters/actions to run from the MainWP Child plugin on the child site. Shipping this behavior in the plugin package is not compatible with WordPress.org plugin directory rules, so the functionality was removed from the White Label Extension workflow.

​
Manual Alternative (Optional)

If you still want this behavior, you can add custom code directly on each child site.
This is custom code, not a White Label toggle. Test on a staging site first and review after WordPress/plugin updates.
You can place it in a custom plugin, an mu-plugin, or your active theme’s functions.php file. Use this exact snippet: 
/**
 * Disable update notifications and hide plugin/update UI.
 */

add_action( 'init', 'mycustom_disable_updates', 9999 );

	// Disable plugin updates.
	remove_action( 'load-update-core.php', 'wp_update_plugins' );
	add_filter( 'pre_site_transient_update_plugins', '__return_null' );

	// Disable theme updates.
	remove_action( 'load-update-core.php', 'wp_update_themes' );
