anyone have any idea what could have caused this?



  • Difficult to debug, it looks like you are using CloudFlare minifications / performance improvement features. Try to disable them and see if depends on it. – Stefano Tombolini Jan 14 at 9:21
  • Could you include your child theme's functions.php? This will help us debug your issue. I have posted an answer below. MY code works also for WordPress 5, I think your child theme is enqueuing your style.css in the wrong order or not at all. – Remzi Cavdar Jan 14 at 10:24
  • My funtions php in child theme <?php function my_theme_enqueue_styles() { wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' ); wp_enqueue_style( 'child-style', get_stylesheet_directory_uri() . '/style.css', array('parent-style') ); } add_action( 'wp_enqueue_scripts', 'my_theme_enqueue_styles' ); ?> – user7663911 Jan 18 at 23:47

Required (child) Theme Files

Check if your child theme has a

  • style.css
  • functions.php
  • screenshot.png (optional, but will help you differentiate)

Recommended basic functions.php for a child theme

 * Example child theme Remzi Cavdar
 * @link https://developer.wordpress.org/themes/advanced-topics/child-themes/

function use_parent_theme_stylesheet() {
    // Use the parent theme's stylesheet
    return get_template_directory_uri() . '/style.css';

function child_theme_branding() {

    // Uncomment this if you want versioning in your child theme stylesheet
    // $themeVersion = wp_get_theme()->get('Version');

    // Enqueue our style.css with our own version
    wp_enqueue_style( 'child-theme-branding', get_stylesheet_directory_uri() . '/style.css', array(), null );


// Filter get_stylesheet_uri() to return the parent theme's stylesheet
add_filter( 'stylesheet_uri', 'use_parent_theme_stylesheet' );

// Enqueue this theme's scripts and styles (after parent theme)
add_action( 'wp_enqueue_scripts', 'child_theme_branding', PHP_INT_MAX );
