    500 page is returned where a 404 page should be returned

    Hi, I've set up my custom error pages as such in my web config files:

        <httpErrors errorMode="Custom" existingResponse="Replace" xdt:Transform="InsertIfMissing">
            <remove statusCode="404" subStatusCode="-1" xdt:Transform="InsertIfMissing"/>
            <remove statusCode="500" subStatusCode="-1" xdt:Transform="InsertIfMissing"/>
    
            <error statusCode="404" prefixLanguageFilePath="" path="/1227" responseMode="ExecuteURL" xdt:Transform="InsertIfMissing" />
            <error statusCode="500" prefixLanguageFilePath="" path="/1230" responseMode="ExecuteURL" xdt:Transform="InsertIfMissing" />
        </httpErrors>
    

    However a 500 page is returned in every case, even where a 404 page should be returned. Both of the ID's in the path="" are ID's of my 404 and 500 pages respectively, in the backoffice.

    In the log viewer I get this error:

    Any advice how to move forward?

    your 404 should be set up in config\umbracosettings.config, as it is handled by Umbraco, then set up your other error handling like below (you need both sets for it to work correctly)

      <system.web>
        <customErrors mode="On" redirectMode="ResponseRewrite" defaultRedirect="/errorHandler">
          <error statusCode="500" redirect="/errorHandler" />
        </customErrors>
    </system.web>
    
      <system.webServer>
        <httpErrors errorMode="Custom" existingResponse="Replace">
          <remove statusCode="404" />
          <remove statusCode="500" />
          <error statusCode="404" prefixLanguageFilePath="" path="/error404" responseMode="ExecuteURL" />
          <error statusCode="500" prefixLanguageFilePath="" path="/errorHandler" responseMode="ExecuteURL" />
        </httpErrors>
    </system.webServer>
    

    set the paths to whatever your path should be
