Not enough details in error message

We all have got the famous error message "An unexpected error has occurred", or a message that was to short like "The file is not exist".

In most cases it will be very helpful if we know more details, specially when getting "An unexpected error has occurred" then doesn't help us at all.

So to get more details open the web.config, find the root configuration\SharePoint\SafeMode and change the attribute CallStack from false to true. Then find configuration\system.web\customErrors and change the attribute mode from on to off.

Now you will get more details to pinpoint your exception.
