How do I configure the Google+ plugin

2 problems

In the settings for the Google+ plugin it says
Under "API Access" click "Create oAuth Client Access." Fill in your details and use this as your "Authorized Redirect URIs": http://moscowexpatlife.ru/

When I'm in the Google Dev area there is no "Create oAuth Client Access" It says something about oAuth2.0

I cannot find where to fill in the Authorized Redirect URI.

When I try to authenticate I get this error

Error: redirect_uri_mismatch
The redirect URI in the request: http://moscowexpatlife.ru/ did not match a registered redirect URI
