1) Its asking me to "continue as Kevin" (my personal facebook account) even though I want to continue as my facebook business page. Business pages are linked to personal accounts on FB just like on Google plus, so what do I do here? I dont want to continue as "Kevin with X friends, birthday X, and age 21+" .... I want to continue as the site page: facebook.com/hairlosstalk/
2) The XF admin asks for a "Secret". No secret is provided by facebook anymore during this setup process. When I tried to "Continue as Kevin" it gave me an error that the "secret" was missing.
If you already created an app, you should be able to see it on the Facebook dev site under "apps" in the upper right. If you haven't created one, skip the quick start stuff -- it's not relevant for our use case.
When the app is created, you should have a "dashboard" which will show you the secret.
