Hi Goajazzz

Try it with this in your (child) theme’s functions.php file.

add_action( 'elementor_pro/posts/query/lwp_related_posts', 'lwp_3266_related_posts' );
function lwp_3266_related_posts( $query ) {
    global $post;
    $query->set(
        'post__in',
        km_rpbt_get_related_posts(
            $post->ID,
            array( 'fields' => 'ids', 'taxonomies' => array('post_tag') )
        )
    );
}

For more information about the function parameters see:

btw:
consider creating a child theme instead of editing your theme directly – if you upgrade the theme all your modifications will be lost. Or create a plugin with the code above.

Thank you keesiemeijer, you’re rock!
