I am unable to connect to vti_bin/listdata.svc for a specific subsite, although it works for other subsites in the same site collection. I am a site collection administrator and I'm working from a client PC.
On the broken subsite, when trying to connect via a browser I am prompted for my credentials - I've tried many different ones but none work. It is also broken when trying to connect to this service in Excel.
Any idea why it would be broken for just one subsite? I can't see that it would be permissions I have tried to access it as a site collection admin and users with full control over the site.
