Hi guys,

I upgraded snort-2.0.2 to snort-2.0.6 and I'm getting the following
error.
Snort is complaining that is not finding (or is getting NULL) between
quotation marks.
There is 'something' between quotation marks.
Everything was running perfect until this upgrade.

Can anyone point me in the right direction?

Below is the message I'm getting from snort when I'm trying to
activate the sensor (via snortcenter):

Current config file error:
