 * Adding a new site is throwing the following error:
 * “Please network activate W3 Total Cache when using WordPress Multisite.”
 * Its coming from Root_AdminActivation.php and caused by some code that was removed
   at some point. Changing the code to the following resolves the issue:
 * if ( ! function_exists( ‘is_plugin_active_for_network’ ) )
    require_once( ABSPATH.‘/
   wp-admin/includes/plugin.php’ );
 * if ( ! is_plugin_active_for_network( ‘w3-total-cache/w3-total-cache.php’ ) ) {
   
   echo ‘Please [network activate](https://wordpress.org/support/topic/adding-new-site-throwing-error/' . network_admin_url( 'plugins.php' ) . '?output_format=md)
   W3 Total Cache when using WordPress Multisite.’; die; }

 * Apologies, to be more specific this is a non subdomain multisite installation.
