Re: New FB Autoconnect Plugin for WP…will it work with MU/BP?
No, the cause isn’t the API key and secret. If you haven’t saved a valid API key and secret, it won’t even render a Facebook button, nor will the login work with the email requirement switched off.
If the problem is that it won’t let him request an email address, the issue could only be the Email Domain setting on the Facebook application, as far as I know. I’m quite confident that functionality works on my end, as I’ve tried it on about 15 other sites since the 1.1.0 upgrade
