call_user_func_array error

If you get this error when using WP Auto Save Management:

PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, class '__CLASS_' not found in /var/sites/i/italy-cycling-guide.info/public_html/wp-includes/class-wp-hook.php on line 298

You have to modify this line:

add_action( 'admin_enqueue_scripts', array( __CLASS_, 'dequeue_autosave' ) );

With this:

add_action( 'admin_enqueue_scripts', array( __CLASS__, 'dequeue_autosave' ) );
