is that due to changes in github API ? given that the project was untouched for a year, this may explain that Nevertheless, i'm new to scala and Play etc, and i couldn't get through to the end of this great tutorial. Maybe i did something wrong ? thx for your help. It says page not found with url : https://github.com/login/oauth/authorize?client_id=*942adb0cb996aa8dfaa5&redirect_uri=http://localhost:9000/_oauth-callback&scope=repo&state=2b39e6b1-bf87-44ae-bcbb-b6be0a60a92c so client id, callback uri, repo and state properly set ?
