Hi,
It seems you have a registerd sitemap provider (which is not configured) in the machine config.
Try to open your web site config file and clear the sitemap providers collection:
<siteMap defaultProvider="SitefinitySiteMap"> <providers> <clear /> <add name="SitefinitySiteMap" type="Telerik.Sitefinity.Web.SitefinitySiteMap, Telerik.Sitefinity" /> </providers> </siteMap>
Good luck!
