#27 nfsight module died

[Dagdu]

I'm running nfsight on Ubuntu 12.04. NFsight shows no data on the frontend. I have rerun the configuration wizard. Updated plugin details in nfsen.conf file.

Here is the error in syslog

May 2 10:11:33 Bodhi-T61 nfsen[26970]: Loading plugin 'nfsight': Success
May 2 10:11:33 Bodhi-T61 nfsen[26970]: nfsight plugin: Init
May 2 10:11:33 Bodhi-T61 nfsen[26970]: Initializing plugin 'nfsight': Module died: Can't use an undefined value as a HASH reference at /data/nfsen/plugins/nfsight.pm line 271.

Here is the line 271 in nfsight.pm
%networks = %{$Conf->{network}};

Here is my plugin configuration.

[ 'live', 'nfsight'],

%PluginConf = (

Please advise ..
