    Hi @Tevon2.0,

    Thank you for posting in the community.

    Per my knowledge, the web config files are configuration files and do not seem to be available for viewing error messages.

    In addition, only when the error occurs, we will see the error message on the web page, and we will be prompted how to view the error message. We can't track errors when they don't occur.

    Hi,

    I'd be happy to help you out with your question. Sorry for the inconvenience caused.

    Please refer to following ways to verify if you have any issues with your web.config file:

    • Use a text editor with syntax highlighting. A text editor with syntax highlighting can help you to identify errors in your web.config file. This is because the editor will highlight any errors in the file in a different color, making them easy to spot.
    • Use a web.config viewer. A web.config viewer is a tool that can help you to visualize your web.config file. This can be helpful for identifying errors and warnings in the file.

    Once you have identified an error in your web.config file, you can track it down by following these steps:

    1. Look for the line number of the error in the web.config validator report or the text editor with syntax highlighting.
    2. Open the web.config file in a text editor and go to the line number of the error.
    3. Look for the error in the web.config file.
    4. Fix the error and save the web.config file.

    Once you have fixed the error, you can restart your web server and your web application should start working again.

    Here are some additional tips for verifying and tracking down errors in web.config files:

    • Make sure that you are using the correct version of the web.config schema. The web.config schema is the document that defines the structure of a web.config file. You can find the latest version of the web.config schema on the Microsoft website.
    • Make sure that you are using a valid XML editor. A valid XML editor is an editor that can correctly display and edit XML files.
    • Make sure that you are using a web.config viewer that is compatible with your version of .NET.
    • Use a web.config validator that is compatible with your version of .NET.
    • Use a text editor with syntax highlighting that is compatible with your version of .NET.

    By following these tips, you can help to ensure that your web.config files are free of errors.
