To fix the black border, add the following to your stylesheet:
.jfbcLogin padding { 0px; }That will override the current style in your template that's causing the problem.
As for the redirection, I just tried to register on your site, and I was redirected to the login page below with a message that I need to activate my account:
wattssoul.com/component/users/?view=login
If you're redirecting to a page that is marked as registered, but have user activation enabled, that's the expected behavior. JFBConnect redirects to the registered-user-only page, but since JFBConnect can't log the user in (due to them not being activated yet), Joomla redirects them to the Login page.
If you're seeing (or expecting) different behavior, let us know.
Thanks,
Alex
