 * Finally found why this is happen… i’ve used the previous WordPress installation.
   It doesn’t support the function,,, Then, i tried to implement it in the latest
   WP version, 3.5.2, it works like a charm!
 * I think, it happen because wordpress doesn’t recognize the function needed by
   the simple-fields, by default defined at /wp-includes/cache.php.. hope it help
   you guys, who have the same problem.
 * it’s a small problem if you just developed it in a new installation, but when
   it comes to a well running production sites, consider to migrate first to the
   latest version before implementing it.

 * I just got this error in WP 3.6 somehow… then it went away. Weird.
