 * Hi all
    when I enable quick cache it always says “Failed to update your /wp-config.
   php file automatically. Please add the following line to your /wp-config.php 
   file (right after the opening <?php tag; on it’s own line).” <?php define(‘WP_CACHE’,
   TRUE);
 * but i already add define(‘WP_CACHE’, TRUE); to wp-config.php already
    and the
   bottom of my page Source doesn’t show quick cache note says it’s working
 * please help Thank you

 * 777 is a security risk. And not needed. Ask your hosting company.
