 * Hi [@scott1137](https://wordpress.org/support/users/scott1137/),
 * This error usually means that you are using an invalid key. When pasting in the
   key, make sure there are no extra spaces at the beginning or at the end of the
   key. Also make sure you are using the Global API Key from CloudFlare. If you 
   still get the error, try changing the key on your settings page in CloudFlare.
 * Best regards,
    Anton

   did not work for you let us know and we will reopen the thread.
