Redirecting to authentication dialog - “An error occurred. Please try again later”

Question

Why does it always happen to me?

This happens after my application verify for user user login and redirect user to the authentication page:

https://w

Answer 1

According to OAUTH Dialog documentation:

*redirect_uri: The URL to redirect to after the user clicks a button in the dialog. The URL you specify must be a URL of with the same Base Domain as specified in your app's settings, a Canvas URL of the form https://apps.facebook.com/YOUR_APP_NAMESPACE ...*

I am constructing oauth links dynamically to ask a user for additional permissions if needed and I realized, that even if you are redirecting to https://apps.facebook.com/YOUR_APP_NAMESPACE you have to have the App Domain and Website settings set in your application administration. I set domain to facebook.com and Website to facebooks root url.

Now my oauth dialog link works fine - even in sandbox mode.
