   if ( ! defined( 'WP_REDIS_OBJECT_CACHE' ) || ! WP_REDIS_OBJECT_CACHE ) { 
       return new WP_Error( 'wp-redis', 'WP Redis object-cache.php file is missing from the wp-content/ directory.' );
   } 
   if ( ! $wp_object_cache->is_redis_connected ) { 
       return new WP_Error( 'wp-redis', $wp_object_cache->missing_redis_message );
