How can I mass-update/save all WordPress posts and pages?

I’m using a free SEO plugin for WordPress called Rank Math – https://wordpress.org/plugins/seo-by-rank-math/

Overall, I like it a lot. But it has some problems for users with existing WP sites who are importing data from another plugin like Yoast.

Rank Math is relying on individual posts and pages to be edited (not using WP’s bulk quick edit feature, but opening each post and re-saving them one-by-one).

This happens with author sitemaps for example. An author’s page is only added to the sitemap if I manually open and re-save one of their posts and then re-save the sitemap settings. It doesn’t find and add existing authors otherwise.

Is there any way to simulate clicking the “update” button for all posts and pages without changing any actual content in a circumstance like this?

Thanks.

Add to your functions.php file, but dont forget to take it off after use it !!!!!

function update_all_posts() {
    $args = array(
        'post_type' => 'post',
        'numberposts' => -1
    );
    $all_posts = get_posts($args);
    foreach ($all_posts as $single_post){
        $single_post->post_title = $single_post->post_title.'';
        wp_update_post( $single_post );
    }
}
add_action( 'wp_loaded', 'update_all_posts' );
