View callstack of unknown error

Question

I've set

<system.web>
  <customErrors mode="Off" />
</system.web>

in my web.config file, but i'm still getting 'unknown error' instead of the stacktrace on my pages. How can I view the stacktrace?

Answer 1

If you're getting this error on sharepoint/wss specific pages, you also have to add following fragment to your web.config to view the stacktrace:

<SharePoint>
    <SafeMode MaxControls="200" CallStack="true" DirectFileDependencies="10" TotalFileDependencies="50" AllowPageLevelTrace="false">
      <PageParserPaths>
      </PageParserPaths>
    </SafeMode>
</Sharepoint>

You can define a specific path in the PageParserPaths element, but this is optional. Don't forget to turn off the custom errors after you found the problem (certainly for a public facing site).

Answer 2

The full range of things to do is listed on this page:

You need to also set CallStack to true in the SafeMode node to see the CallStack you require.

Answer 3

Try setting <customErrors mode="Off" /> in the following web.config file in addition to your webapp web.config file.

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\ADMIN\web.config
