 * 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
