First off, yeah, we know JFBConnect is installing the older SCLogin module. We have a minor release coming out next week, v5.0.1, that will include the new SCLogin module as well as a ton of little fixes throughout. The SCLogin module was released separately so that it could get thoroughly tested and be an optional upgrade until we were sure we wanted to include it in the main release. Caution is good when releasing an extension used on lots of sites
Now, for your issues:
* The Remember Me box is a part of Joomla. Go into the Plugin Manager and disable the System - Remember Me plugin to remove it.
* "I'm having the java issue as well of none of the buttons working (mongal)." Do you mean 'modal', for the popup version? If that's not working, we'll need to see the page on a live site to diagnose. There's quite a few possible causes that we know of, and surely more we aren't aware of, and it's not possible to determine without seeing your site. One thing to test is if the popup works pages *other* than the home page.
I think those were the main things you were asking about, but if you still have questions or issues, you know where to find us!
Thanks,
Alex
