This often occurs when Urchin is running as the wrong user or when the ‘/usr/local/urchin’ directory is owned by the wrong user. This is usually because the server is running Plesk. To resolve this issue, first check to see which user is running Urchin.
[root@server root]# ps -aux | grep urchin

As you can see, it is running as the user nobody. On Plesk machines, this should be run as the user ‘psaadm’. To correct this issue you need to edit the following files.
/usr/local/urchin/var/urchinwebd.conf.template
/usr/local/urchin/var/urchinwebd.conf
In those files, locate these directives.
User nobody
Group nobody
You will need to change them to this.
User psaadm
Group psaserv
Then make sure that the ‘/usr/local/urchin’ directory is owned by psaadm.
chown -R psaadm:psaserv /usr/local/urchin
