 * I get this error message on the site.
 * The all-in-one calendar has been disabled due to an error:
 * Generated class map is invalid: false. Please delete lib/bootstrap/loader-map.
   php (if it exists), make sure lib/bootstrap/ is writable by the web server, and
   enable debug mode by setting AI1EC_DEBUG to true (then back to false when done).
