As mentioned in your other post, I'm not sure if you're using JFBConnect at all for your JomSocial Facebook integration. If you need help with JomSocial's basic Facebook integration, you'd need to contact their support team.
JFBConnect has many more features and less bugs than JomSocial's basic integration. If you want a smoother Facebook experience on your site, you should purchase our JFBConnect extension.
Thanks,
Alex
