By default, IIS web server will hide detailed error information to prevent exposing more information of your web application. Though, there are times when your web application throws generic error and you want to see actual error to fix it. To enable detailed error information, you’ll have to modify the web.config file of your application and set attributes. Here are the steps.
Locate the web.config file in the wwwroot directory of your web application. Edit it with your choice of editor.
- Add following entries to your web.config file to disable generic errors and save the file. If these entries already exist, set their values as shown below.
<customErrors mode="Off" />
<httpErrors errorMode="Detailed" />
