Damen,
1. I was able to successfully create a user, activate and then log in a couple of times with Facebook. You can delete the 'melsou' user.
2. I was also able to successfully do this with Twitter as well. You can delete the 'melsou1' user.
3. I received the following error for LinkedIn: "invalid redirect_uri. This value must match a URL registered with the API Key." Please make sure that you follow the guide here for the Redirect URL examples:

If #1 and 2 still won't work for you, please clear your browser cache and try again or give me more details to reproduce consistently.
