Bug with ID PPPM-12290. The issue has been fixed in Plesk 18.0.30. Please consider updating your server.
If update is not possible for some reason you may try the following
As a workaround, create a Scheduled task that will automatically add the missing rule to be switched off (for example,
214540) after the
50plesk-daily script is executed:
Connect to the server via SSH.
Find out when
/etc/cron.daily/50plesk-dailyscript is executed on the server by running the following command:
# cat /etc/crontab
In the output, the following line will be shown:
CONFIG_TEXT: 11 0 * * * root test -x /usr/sbin/anacron || ( cd / && run-parts --report /etc/cron.daily )
In this example, script
50plesk-dailyis executed at 0:11 daily.
Note: Crontab format can be checked here.
Go to Tools & Settings > Scheduled Tasks (Cron jobs) and click Add task.
Set the following parameters:
