Displaying Custom Error Messages / Enabling Detailed Errors on IIS 7

 

I was deploying an ASP.NET MVC 2 default application to one of my GoDaddy hosted sites when I encountered the below screen:

How can I know the underlying problem?

Simply edit the web.config file.

(1) Inside <system.webServer> node add

<httpErrors errorMode=”Detailed” />

<asp scriptErrorSentToBrowser=”true” />

(2) Inside <system.web> node add

<customErrors mode=”Off” />

<compilation debug=”true” />

 

Wasn’t that so easy?!

 

NOTE: Remove the said lines after you have found and applied the fix to your problem. You don’t want your regular website visitor know the internals of your application, right?
