Help getting Publish to Facebook and Like to work

[JenniferK]

I need help either creating and setting up a new Facebook App, or fixing the one I already have.

I am using:

vB 4.2.3RC1
PHP Version 5.4.38
SQL Version 5.5.42-37.1
Using default style

With my current setup, Facebook Connect works, but other features are still not working. When liking a thread and leaving a comment, it does not post on Facebook. Nothing happens.

When I tried to reply to a thread and check Publish to Facebook I get this:

Invalid Scopes: publish_stream. This message is only shown to developers. Users of your app will ignore these permissions if present. Please read the documentation for valid permissions at:https://developers.facebook.com/docs...in/permissions

The document they link to does not help me at all. I am not very techie. The page doesn't help me because I don't know what to do to with it. It describes different permissions, but doesn't tell me where to find them or how to change them.

I tried starting over and creating a new app based on step-by-step (and recent) instructions and got the same results.

I am really hoping someone can help me with this!
