We have a new portal server installation that is working fine except for one strange error. We created our new site using the “Publishing Site” template and also created subsites below it. All that went fine. However, if we try to create a new page (“Create Page” command from the “Site Actions” Menu) from any of these sites we get this error:
not found in web
To solve this:
Go to Site Central Admin, User Permissions for Web Application and be sure “Use Client Integration Features” and “Use Remote Interfaces” are enabled. That should do it.
