 * I’m seeing quite a few of those in Activity dashboard.
    What’s weird, it’s locking
   out the server IP and the URL says “mydomain.com/wp-cron.php” Can you briefly
   explain how exactly the “Probing for vulnerable PHP code” functionality works?

 * These rules are OK. To solve the issue add the following line to the Request 
   whitelist field in the Traffic Inspector settings.
 * `/wp-cron.php`

 * Adding this string solved this issue also for us.
    Is there a reason not to add
   this string per default to the whitelist field?
