hobbler,
It could be a mis-configuration issue, or it could be a conflict with the RocketTheme template. I'm not sure which, but I can help you narrow things down and then help you get things going from there.
First, I would recommend switching (temporarily) to the Protostar template that comes with Joomla. In the SCLogin module, disable the jQuery and Bootstrap options as those are definitely not required with Protostar. Then, test the SCLogin module and make sure the features work how you want there. If so, you know it's not a configuration problem with the SCLogin module.
If you get that going similar to how you want, then switch back to the RocketTheme template. You'll may need to enable the Bootstrap option, but probably *not* jQuery. Test again. If that doesn't work, the best thing to do is post (or Private Message) a URL where we can see the page in action. From there, we can narrow down if it's a conflict pretty quickly and try to come up with a suitable work around to get you goin.
Hope that helps get you going,
Alex
