Plesk Control panel shows the following error:
Unable to parse the configuration file /usr/local/sb/config
Incorrect ownership or permissions for /usr/local/sb/config.
Make sure that ownership of file is psaadm:root:
[root@test]# ls -la /usr/local/sb/config
-rw------- 1 psaadm root 2335 Jan 17 01:56 /usr/local/sb/config
If you see that ownership is not correct, change it with chown command:
[root@test]# chown psaadm:root /usr/local/sb/config
