 * I’ve just started to get this message. I got it last night when activating a 
   plugin and again when I deactivated some plugins.
 * I did a search on Google, but all I’m getting are posts about Drupal.
 * `Warning: array_flip(): Can only flip STRING and INTEGER values! in /home/xxxxxx/
   public_html/wp-admin/includes/menu.php on line 279`
 * This is a Multisite, and the error only shows on the main site.
