From the description you provide, I'm not sure. Can you help answer a few questions?
1) What is the problem you're having with LinkedIn and Google? Are there any error messages you can provide that will help narrow things down? Please set "Enable Error Reporting" in JFBConnect to 'Yes' as well to make sure all error messages are shown.
2) What version of Joomla are you using?
3) What version of JFBConnect are you using? I see your subscription expired last year, so I'm assuming you're still on JFBConnect 6.5.
Thanks,
Alex
