I'm so sorry for the delay in getting back to this. I just had a look again at your site, and the files were compressed. I completely understand why you would have re-enabled that setting after the wait.
With that said, I did a little more investigation and testing on your site, and have a solution that should fix the extra space. You'll need to add the following CSS to the page:
div#login-modal {
bottom: inherit;
}
That can go in a custom CSS file that your template may provide. Otherwise, you can add it to our SCLogin CSS theme file:
/media/sourcecoast/themes/sclogin/default.css
I hope that helps. If you need anything else, just let us know.
Thanks,
Alex
