When i login to the backend and click on Pages, a big popup comes up with "page cannot be found". Some of the others do that as well. Some just site there and say "Loading..." The site works fine on my local machine. Deplopyed it to a shared server running Windows Server 2003 with IIS6. ASP.NET is set for 4.0 all ISAPI extentions are there. Wild card is there. Authentication is anonymous only. I have the Silverlight MIME types. The server is running in Full Trust mode by the looks of the root web.config. <location allowOverride="true"> <system.web> <securityPolicy> <trustLevel name="Full" policyFile="internal" /> <trustLevel name="High" policyFile="web_hightrust.config" /> <trustLevel name="Medium" policyFile="web_mediumtrust.config" /> <trustLevel name="Low" policyFile="web_lowtrust.config" /> <trustLevel name="Minimal" policyFile="web_minimaltrust.config" /> </securityPolicy> <trust level="Full" originUrl="" /> </system.web> </location> Please see attached settings and error shot. Fixed URLScan was installed and disallowing dots in the URL path.
