Looks like you declared the wrong type of logger
private static readonly ILog log = LogManager.GetLogger(typeof(DoNothingPageCreatedEventHandler));
It should be:
private static readonly ILog log = LogManager.GetLogger(typeof(HVGSPageCreatedEventHandler ));
I also would recommend you use a custom namespace.
Just add this at the top:
and change the namespace containing your handler to whatever you want like:
Then you'll need to change it in your config file as well.
Hope it helps,
