I know you solved this already, but in case anyone else encounters similar problems:
The sites have to be correctly configured in all of the following sections: episerver.framework, episerver.common, episerver.mail and/or episerver.community. The siteId:s must match.
Reusing this thread for the same issue. I get the same error on an CMS 6 R2 site. I have double checked that the siteIds matches between the config-files.
After migration from Relate+ 1 to Relate+ 2 I'm having trouble getting the site up and running.
I assume it's a web.config related issue, however I've compared it to a clean installation of
Relate+ 2 but can't find the root to the problem. Any suggestions?
My yellow screen of death:
Server Error in '/' Application.
There must be at least one site configured for the application to start.
