Posting this to resolve a question I couldn't find an answer to elsewhere.
I'm running "elmah" for error logging in a legacy .NET framework project. It works fine in all of my testing / production environments. However, navigating to it locally produces an XML error:
Root element is missing
within ProcessRequestMain
, which seemed to be internal to elmah. Changing configuration didn't help, and I couldn't find a reference to this elsewhere, where it only didn't work locally.
