 * Hi
 * I am getting the error
 * NetworkError: 418 reauthentication required admin-ajax.php
 * When ever the admin-ajax.php file is called the above error occurs.
 * When adding a page, when trying to add media. Anytime.
 * I have checked file level access etc.
 * Anyone know what might cause this?
