I'm not even sure that's the JFBConnect Facebook Login button. It looks to be the one from JomSocial from the picture. Can you check and make sure you've followed the instructions in our
JFBConnect / JomSocial Facebook integration
instructions? That will show you the settings you should use in JomSocial and how to add our button there.
In JomSocial 3.0, things should be much simpler, but for now, that's the process.
If you've implemented that, let us know if the button is still out of place. If so, let us know a URL where we can see the button in the wrong place and we should be able to provide some CSS to be able to help you fix the looks.
Thanks,
Alex
