Problem with classic ASP after server .Net update RRS feed

  • Question

  • User42143373 posted

    About a year ago I created a classic ASP web page running on IIS on a server.
    It has been working fine until today when a colauge ran an update of Microsoft .Net on the server.

    Now my ASP site is not working any more. It is complaining about a web.config file.
    So it is like it has switched my ASP interpreter from classic ASP to .Net

    How do I change that back?

    Find the application pool for your application, and then change .NET Framework/CLR setting to No managed code,

    Hi Lex Li

    Thanks a lot for your help!

    I spend quite a bit of time, locating the issue. I had no idea that this default setting would change, but here I can change it back.

    Best regards

    If the error occurred after updating Visual Studio, you may not be running it as administrator. This is one of the causes of the error: "No relevant source lines"
