If you need to edit the slug to match the page title of your Staff page, then you will need to add this function to the functions.php file of a child theme:
add_action('init', 'custom_filter_staff_slug', 1);
function custom_filter_staff_slug() {
add_filter('kadence_staff_post_slug', 'kadence_custom_staff_permalink');
function kadence_custom_staff_permalink() {
return 'CUSTOM_STAFF_SLUG';
}
}
Change the “CUSTOM_STAFF_SLUG” to whatever you want to appear in the url. Once the function is added and saved, navigate to Settings> Permalinks, and re-save them.
