JFBConnect with Community Builder 1.3.1

Oliver,
I gotcha now, I thought you were looking for something a little different.

To do what you're looking for, you'll need to make one minor code change, and hopefully that will do exactly what you're looking for. In /components/com_jfbconnect/controller.php. At line 73, change the line as follows (adding the '1' at the end):
$app->redirect(JRoute::_('index.php?option=com_jfbconnect&view=loginregister', false, 1));

That will force the redirect from Facebook after a user logs in to the SSL version of that page. Please post back with your results!
