I am still getting this email several times a day after removing Kernal Care as instructed above.
The IP "my site ip" was already used for trialing on 2018-12-20

Check if there is a "/etc/cron.d/kcare-cron" file. If it exists - remove it, or comment out the action line in it.
Hello,
I've gone into the path for KC's control panel, and it comes up with a few options. But there is no dropdown button as described above (for uninstalls/Remove).
I thought I had fixed this some months ago, but now the cron emails are starting again. Perhaps I uninstalled it before? Could that be why I see no dropdown?
In either case, would I now need to use the command line? Not my strength, and would prefer not.
Hello Lance Evans
> Perhaps I uninstalled it before? Could that be why I see no dropdown?
Yes, that's possible.
I would suggest trying the CLI solution too.
If this won't help, submit a request to Plesk Support: https://support.plesk.com/hc/en-us/articles/213608509
I have had Kernal Care running on all 6 servers, and have always paid on time, all servers are up to date.
Every morning I get 6 emails all saying "The IP xx.xx.xx.xx was already used for a trial license on 2018-09-20"
I've tried going into the extension on each one and sync license keys, but its still happening.
How can i stop this?
Hello Chris Collins
