Hello @Claudio Acosta , I guess they meant it that way, but I don't know why they didn't just change the version. Leonid will explain it to you exactly how it's done when he gets here.I don't know what certificate you are using.

curl -s -k https://xxxxx.xx/public_html/periodic/cron.php

And you might need to enable cURL ---- go to developer--cURL - trust unsigned certificates or not verified hosts.
