Wpconfig debug mode

Hello all,

I put Wpconfig debug mode : true

and I saw this line before header :

Warning: call_user_func_array() expects parameter 1 to be a valid callback, class ‘Wp_Night_Mode_Public’ does not have a method ‘wp_night_mode_customizer_css’ in /home/thj698/wordpress/wp-includes/class-wp-hook.php on line 287

Do you have an idea of that ?

Thanks for support
