First, thanks very much for this project. It helped a lot.
When starting off with the basic login_with_yahoo.php, it will instruct you to create an app on Yahoo (if you have not entered values for client_id and client_secret). I used the suggested url to create an app: https://developer.apps.yahoo.com/wsregapp/
I am not sure that is up to date. I walked through that process and ended up with what Yahoo referred to as "Additional API Information." I was on the Yahoo developer Project page, so all seemed ok. Of course, it went downhill from there. :)
This is the url to the Yahoo project page where I was able to build a project with keys that worked: https://developer.apps.yahoo.com/projects/
Thanks again.
