Resolved Cron problem

[DieterWerner]

Message from Cron Daemon:
The IP xxx.yyy.zzz.xxx was already used for trialing on 2017-04-22

What does that mean?

This seems to be an application package message. Have you installed an application or plugin hat requires a license? That plugin seems to use a crontab job, but the license or trial period of the software has expired.

Yes, I think the wp extension tool was the bad boy.
Update: No - it is the KernelCare software.
