Preparing to setup CB Connect

Okay, I've gone through the steps with Facebook and seeing this message when I try to have a user link with Facebook:

Seeing that message where? On your site? An error like that usually means the servers mod_security is blocking the request.

UPDATE#2: I managed to be able to test out Facebook and Google on a live site and it seems to be working okay. The only worry I have is whether these apps limit whether sites need to be on primary domains, vs a subdomain? The latest test I tried was on a primary domain.

You have 2 domains for the same site? You'll need to authorize both in your application then.

Yes, the screen was blank and just that message appeared. I'll check with my wehbost provider about mod_security.

No, I set up new Facebook and Google apps on a completely a different site and it worked fine to confirm I set up the other apps correctly. This one was a root domain.

The one I am having issues with is a subdomain and I am not sure if this is the reason or if it matters. Both sites are on the same server.

Ok, then yes that'd be mod_security.

The domain parameters in the application are pretty strict. Just read their descriptions carefully. Some only want/need the root domain and others want the subdomain.
