You need to change the code from this

apply_filters( 'testimonial_rotator_pre_widget_instance', $instance, $instance['rotator_id']);

to

$instance = apply_filters( 'testimonial_rotator_pre_widget_instance', $instance, $instance['rotator_id']);

in plugin file testimonial-rotator.php.

Then you need to add the follow

add_filter( 'testimonial_rotator_pre_widget_instance', 'home_rotator_hide_title' );
function home_rotator_hide_title( $instance, $id = {your-testimonial-rotator-id} ) {
  $instance['hide_title'] = true;
  return $instance;
}

to your current theme functions.php file
