BP Social Connect Google+ doesn't login.

Hi there. I have just set up BP Social Connect for Google+, however after attempting to login, users are redirected to the home page without being logged in. An account is created for them which can be seen in the WordPress backend under 'Users', but they are not logged in. I have done the following:

• Created a google project and gotten a client ID and client secret string.
• Enabled google+ api for the project.
• Set the authorized URI's to be the home page of our website.
• Placed the Client ID, Client Secret and Authorized URI into buddypress social connect settings.
• Set up the profile field map to be name:Name

Upon first attempting to login with a google account, it says our website asks for basic profile permissions as it should. After hitting 'alow', the user is redirected to the homepage, however they are not logged in. An account is created for them using their e-mail as the name. Upon attempting to log in again with the same google+ account, it says our website asks for 'offline access' permissions, and again, just returns you to the home page un-logged in. Any help would be appreciated.
