Hello, I am trying to submit my sitemap to google and got this error for the sitemap page. What do I need to do.

Exception:

Value cannot be null. Parameter name: url

Stack Trace:

at System.Web.HttpResponse.Redirect(String url, Boolean endResponse, Boolean permanent) at DotNetNuke.Entities.Urls.AdvancedUrlRewriter.ProcessRequest(HttpContext context, Uri requestUri, Boolean useFriendlyUrls, UrlAction result, FriendlyUrlSettings settings, Boolean allowSettingsChange, Guid parentTraceId)

You can see this exception because the customErrors attribute in the web.config is set to 'off'. Change this value to 'on' or 'RemoteOnly' to show Error Handling

The error handling would have shown this page : Default.aspx?TabId=86
