if (class_exists('WooThemes_Sensei_Frontend')) {
    remove_action( 'sensei_comments', array( $woothemes_sensei->frontend, 'sensei_output_comments' ), 10 );
    add_action( 'sensei_comments', array( 'WooThemes_Sensei_Frontend_Comments', 'pasada_sensei_output_comments' ), 10 );

    class WooThemes_Sensei_Frontend_Comments extends WooThemes_Sensei_Frontend
    {
        function pasada_sensei_output_comments()
        {
            global $woothemes_sensei, $view_lesson, $user_taking_course;
            $allow_comments = $woothemes_sensei->settings->settings['lesson_comments'];

            if ( is_user_logged_in() && $allow_comments && ( isset( $view_lesson ) && $view_lesson ) && ( isset( $user_taking_course ) && $user_taking_course )) {
                genesis_get_comments_template();
            } elseif ( is_singular( 'sensei_message' ) ) {
                genesis_get_comments_template();
            }
        }
    }
}

Add the following to your functions.php file:

remove_action( 'sensei_pagination', array( 'Sensei_Lesson', 'output_comments' ), 90 );

add_action( 'sensei_pagination', function() {

	$course_id = Sensei()->lesson->get_course_id( get_the_ID() );
	$allow_comments = Sensei()->settings->settings[ 'lesson_comments' ];
	$user_taking_course = Sensei_Utils::user_started_course($course_id );

	$lesson_allow_comments = $allow_comments  && $user_taking_course;

	if (  $lesson_allow_comments || is_singular( 'sensei_message' ) ) {

		comments_template( '', true );

	}

}, 90 );

The problem is Genesis requires comments to be separated into comment, ping, and trackback groups. The way Sensei outputs comments is by using the output_comments function, and then calling comments_template(). I removed the default way Sensei outputs comments, and wrote comments_template( '', true ) to make it compatible with Genesis.

Thank you! That's works perfectly. Interesting your comment about how Genesis requires comments.

See you!
