i was learning OAuth2 in order to login an account with Google+ , Facebook, etc. on a web site.
I have followed a tutorial about it, and i have an issue when i clicked on my button "Connect with Google+" : 
In the tutorial, he created a User.php but i had already one with FOS User.
Here is my code :
User.php :
