How do I enable a custom error page in my development environment?

Bryan Drenner asked on October 2, 2014 21:58

I followed the instructions on this page to enable a custom error page. However I am still seeing the YSOD.

My Web.config has the following elements, which I added according to the documentation:

<system.webServer>
    ...
    <httpErrors existingResponse="Auto" errorMode="Custom">
      <clear />
      <error statusCode="500" path="/ErrorPage.aspx" responseMode="ExecuteURL" />
    </httpErrors>
    ...
</system.webServer>

It also has these elements, which I haven't touched:

<system.web>
    ...
    <customErrors defaultRedirect="~/CMSMessages/error.aspx" mode="Off">
        <error statusCode="404" redirect="~/CMSMessages/PageNotFound.aspx" />
    </customErrors>
    ...
</system.web>

My understanding is that customErrors is a legacy element, and that httpErrors should work for IIS7 and later. I'm using the latest IIS Express. So why isn't this working?

If I set customErrors to this, then my error page works. I wonder why httpErrors does not work. This is probably an ASP.NET question and not a Kentico-specific question, except that Kentico's documentation says httpErrors should work for IIS7+.

<customErrors defaultRedirect="~/ErrorPage.aspx?" mode="On" />

Hello Bryan,

not sure, if you have checked the Documentation: Creating custom error handling pages but one difference here could be that you are using IIS Express.

Best regards, Martin
