I spent a large proportion of yesterday trying to debug why a website I was trying to publish wasn't working.. Upon copying the folder there, and converting it to an application, we browse to the site and lo, nothing there. Not a sausage... Just a blank page. Hours on this.. Is it the web.config? - ahh no. Is it the configuration of the server? - ahh no no. Let's try again, create a new folder... add in a 'Hello world' html page Browse to: Success! ok, Convert to application - Browse to: Failure! ......
