 * Hello, I am trying to use wp_update_user() in a page template file in my theme.
   When I call it, I get the following error:
 * `Fatal error: Call to undefined function wp_update_user()`
 * I have been testing with this example of it:
 * `wp_update_user( array ('ID' => $user_ID, 'user_url' => $up_site) )`
 * The variables in the array all contain valid, existing information.

 * the wp_update_user() function hasn’t been loaded.
 * if you require the /wp-includes/registration.php file like this:
 * `require_once( ABSPATH . WPINC . '/registration.php');`
 * you should be able to use wp_update_user.
