Hmm.. not sure why it's looking like that. We'll have to check on some changes in the latest release of JomSocial. Looking at your site though, if you add the following CSS to your template, it should fix your problems:
#community-wrap .cGuest .login-area {
padding-bottom: 40px;
}
#community-wrap .auth-facebook {
margin-top: 20px;
}I hope that helps get you going, but if you have any questions, just let me know!
Thanks,
Alex
