When trying to add a new datasource to SharePoint designer to display blog posts, I ran into an error. Designer tells me "the server returned a non-specific error when trying to get data from the data source". I browsed to the url (http://site.domain.com/blog/_vti_bin/ListData.svc),
that seemed to be working fine. But when I browse to
http://site.domain.com/blog/_vti_bin/ListData.svc/Posts, it throws an 500 internal server error.
What could be going on and how can I find some more debug info on it? I tried modifying the web.config in C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\ISAPI to give some more debug info (since ListData.svc is in there), but that
doesn't seem to do anything.
Edit: I also tried adding the svc reference in VS2010, but that errors out too with a complaint about missing authentication. I have no idea where that's coming from.
