Some background information:
I am currently running WordPress with the "Members Only" and "Register Plus" plugins. Essentially these two ensure that only registered users can read the stuff I post and every registration has been approved.
I would like to use SFC so friends with Facebook accounts can use their existing information to view and comment on posts in my blog. So far, I have noticed the following problems.
Upon activating SFC, the "Login with Facebook" button appears on the login screen (which overrides the main page if a user is not logged in) - which is good. However, upon logging with Facebook credentials, I am then directed to the WordPress user registration page which then defeats the purpose of using shared credentials.
Going past this problem, I notice that when I view my own profile via the Dashboard, my Facebook avatar is extracted and displayed. However, when I comment on my posts, the avatar is a blank one (i.e. the default).
How do I solve these 2 problems?
