Consider the example below, 2 Custom Sigs are in the XML file, one in RED and one in BLUE, with the remaining XML headers in bold.
And this works fine..
But what can you do, when you get this error?
Well for a start i`d check for the format of the XML file is correct!, but also there may be some tell tale signs in the Backend Log. This can be viewed by pnlog show backend from the CLI or Admin/System Maintenance/View Log Files from the GUI.
Incidently if you are successful the backend log will look something like this..
I hope this helps.
