Answer: 
You must set the customErrors mode to "Off", as the message in the first screenshot says. Removing the default redirect will probably help.
Have you considered using [Elmah (Error Logging Modules and Handlers)](http://code.google.com/p/elmah/) for better remote log viewing mechanism, it is very easy to implement either through NuGet or follow instructions [here](http://haacked.com/archive/2007/07/24/securely-implement-elmah-for-plug-and-play-error-logging.aspx). I am using Elmah for a long time and suggest this.
