[Plugin: W3 Total Cache] PHP Fatal error wp_cache_get() and get()

Is anyone going though the same problem here?
Since i’ve updated the wordpress to version 3.3.1 my error_log is being filled with those errors:

PHP Fatal error: Call to undefined function wp_cache_get() in /var/www/wordpress/html/wp-includes/functions.php on line 347

and

PHP Fatal error: Call to a member function get() on a non-object in /var/www/wordpress/html/wp-content/object-cache.php on line 52

i’ve being researching about this error for 2 days and couldn’t find any solution.
I’ve already reinstalled wordpress and the plugin, disabled minify, but the error still goes on, the website is working ok, i can access the admin page without problem but my error_log grows really fast with that error.
