I am unable to view the snip. Picture is so blurry.

Add some more details. What happened with your application ?

What are your steps ? How could we reproduce it?

I think you have mistakenly change some details in web.config file ? Isn't soo?

Or it may pic details from machine config?

I can't predict anything, it seems to be insufficient details.

Place a debugger point in your source and try to debug your code and see the exception there.

Send us the exception details.

After digging out about the exception, I found same snapshot at some website.

Remove the defaultRedirect attribute and it's value from web.config file and set mode = "off" or "on" according to your need.

Place in web.config file under


You 'll be able to see the actual exception other than this now.

Thanks Mehmood for your valuable replies. I have changed the custom errors mode to off and it really works. Now I am recieving detailed errors instead of custom ones. Thanks again...
