I have a SharePoint 2010 site that works correctly, and a subsite that does not. When I open the subsite in SharePoint Designer, the "Lists and Libraries" view says "There are no items to show in this view." even though there are both Lists and Libraries defined for the subsite.
If I visit the
http://site/subsite/_vti_bin/ListData.svc page it returns an empty document.
http://site/_vti_bin/ListData.svc returns a valid XML document.
I have Full Control permissions for the subsite, and the Lists and Libraries all show up if I view the "All Files" folder. I have installed the data services update.
Update: I have also checked the SharePoint Designer settings. All permissions are selected globally and for the site collection in question. The top level site in the collection is working correctly; Only the subsite has issues.
