The server error in ‘/’ application can occur when your programs and file types are not compatible with your .NET Version. This prevents your website from running on the Server.

Fortunately, the IIS Manager lets you check the version of .NET you are using, and this is crucial to resolving this issue. In this article, we will discuss the methods and steps we can use to fix the server In ‘/’ application error for good.


How do I fix ServerError In ‘/’ Application Runtime Error?

1. Switch to a different browser

If you notice that this error appears on your default browser, then maybe it would be the time that you install another one just to see if it reacts differently, and we suggest you try out Opera.

Opera is a Chromium-based web browser that is designed to be fast, lightweight, and still powerful. More so, it can be heavily customized using the wide variety of extensions that you have at your disposal in your digital library.

It is frequently updated, and all of the components are of the latest version of all times, so errors such as the one described above are less likely to occur again if you switch to Opera.
