force use of updated style sheet

3 Replies ·

  1. I want force browsers to reload cached style sheet after making changes to it.

    add_action( 'wp_enqueue_scripts', 'railtrail_enqueue_styles' );
    function railtrail_enqueue_styles() {
        $parent_style = 'parent-style'; 
        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 ), wp_get_theme()->get('Version') );

    does not seem to work.

    You have to change the Version: xxx in your child theme’s style.css file for it to bust the cache with that method.

    yep, had done that, and cleared cache etc.
    also tried timestamp method.
    Oh well

    I should note that browsers do not have honor cache-busting techniques like that, but I’ve never seen them not do it. And, as far as I know, none of the major browsers have stopped.

    Check your site’s page source code on the front end and make sure the style.css file has something like ?ver=1.1.1 (whatever your version is) appended to the end of the URL. It’s possible that a plugin is removing the version number.

    If it’s not the problem, it’s a cache issue somewhere along the way. Whether that’s on the server level or on the browser level.
