Hi Mark,
Thanks for the reply. It looks as if when doing the 'update' it changes the properties of the config.xml.
I just ran:
chmod 777 /etc/pcmonitor/config.xml
And it all now works fine !
Although did just notice it duplicated my server on my dashboard/app. One server was offline and the other online. Have removed the offline one now.
On a CentOS 6.5 x64 box.
Hope this helps.
Craig
