Virtualmin occurs when checking to verify that the error is present logrotate configuration is not valid:

Log file rotation feature restricted

This is due to the syslog daemon not running. Check If the service is running and restart. Your server may have syslogd daemon on rsyslogd depending on Your OS.

2. Solutions

Let's look at the status first.

/etc/init.d/rsyslog status

Appear

RSYSLOGD is stopped
RKLOGD is stopped
Description does not start successfully

And then at the start Rsyslog

/etc/init.d/rsyslog start

The following prompts can be found

Starting system logger: [OK]
Starting kernel logger: [OK]

We're checking to see if Rsyslog starts.

Chkconfig–list | grep rsyslog

Start successful

Rsyslog 0:off 1:off 2:off 3:off 4:off 5:off 6:off

No installation or others are reminded of this.

-list:unknown option
We will set the Rsyslog boot up

Chkconfig Rsyslog on

This is OK, then we click on the check to pass!
