new rollingFileAppender created the file but never writes to it - log4net

Question

I am trying to add a new rolling file appender to an existing log4net configuration. I have been looking at questions on S.O. and looking at the documentation however I can't seem to see where my issue is.
The problem is that it creates the file but never writes to it. All I can come up with is that somehow I have misunderstood how the hierarchies work? If I attached a debugger I can see the line get written to the console but even when I did a test deploy the log file document never has anything written to it. There are other questions about this however they all have issue with levelMin or something like that. I have tried setting my config to ALL, didn't help either.
Here is complete config so you can see what I am talking about.

Here is the code example.
private static readonly HALogger Logger = new HALogger("DocumentImportLogger");
//which calls
public HALogger(string loggerName)
{
_logger = LogManager.GetLogger(loggerName);
}
//Then to log.
Logger.Info(string.Format("Checking for new documents - LastDocumentId: {0}", LastDocInfo.LastDocumentId));

Your config file looks fine to me.
The problem is that log4net silently ignores configuration errors by default and just silently fails - which is a sensible design choice for a logging framework but can be frustrating at times.
You can try enabling internal debugging and programmatically checking for configuration errors.
See the log4net faq => the relevant sections are:
"How do I enable log4net internal debugging?"
"How can I evaluate configuration errors at runtime?"
Also, please add a code example of how you obtain a logger and try writing to it.
