Cause
Owner for Plesk log file
/var/log/plesk/panel.log
is not correct.
Resolution
Connect to the server via SSH.
For Plesk Onyx and 12.x:
Move panel.log to another place, restart sw-engine and sw-cp-server services:
# mv /var/log/plesk/panel.log /var/log/plesk/panel.log.bk
# service sw-engine restart && service sw-cp-server restart
If the issue persists, correct permissions to the following folder:
# chmod 0755 /var/log/
# chown psaadm /var/log/plesk/
For older Plesk versions:
Check permissions for
/usr/local/psa/admin/logs/panel.log, they should look as below:
# ls -la /usr/local/psa/admin/logs/panel.log
-rw-r----- 1 psaadm root 67727 Jan 17 02:30 /usr/local/psa/admin/logs/panel.log
Change permissions if required with chown command and restart Plesk service:
# chown psaadm:root /usr/local/psa/admin/logs/panel.log && chown psaadm:root /usr/local/psa/admin/logs/
# service psa restart
If the issue persists, correct permissions to the following folder:
# chmod 0755 /var/log/

I am getting these exact symptoms. Specifically the third error on the Plesk dashboard.
I do appreciate the time taken to write these steps.
However, these steps did not solve the issue for me personally.
@Clintvee, hi, what is your Plesk version?
It is 12.0.18
@Clintvee, did you restart Plesk services?
Please show me an output of these commands:
# ls -la /var/log/plesk/panel.log
# ls -ld /var/log
-rw-r----- 1 psaadm root 0 Apr 11 13:27 /var/log/plesk/panel.log
drwx------ 5 root root 4096 Apr 11 13:56 /var/log

fooked my server by changing all users and groops in /var/

[root@ms142 var]# ls -la

used the comand sudo chown -R on the folder
so no access to plesk and the websites
@Clintvee, permissions on /var/log are incorrect. Do the following and restart Plesk services:
# chmod 0755 /var/log/
@Andy, in this case, I can suggest only comparing with a working server and changing the permissions manually. It also depends on how much permissions were changed.
The support team for our hosting company ended up resolving it in the end.
I checked the permissions of the /var/log/ file and can see they are now
drwxr-xr-x 6 root root 4096 Apr 12 03:20 log
Thanks for your support!
