the first thing i had in mind is to unload the sidebar (comment the get_sidebar() function in your child themes)… but why do you want to get rid the sidebar? i like seing a black sidebar on a white content, thou.

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.
