The ../admin/includes/configure.php file

define('HTTP_SERVER', 'http://www.THIS_SITE.com');

Needs to have ssl by adding the 's'

define('HTTP_SERVER', 'https://www.THIS_SITE.com');

In order to have the page detect the ssl, otherwise you will get a blank page.

I had to set it manually to get it to work right. Seems it only appears to be a server problem not processing the pages when the server is actually doing an outstanding job of processing the ssl. And since it's the admin configure.php, the admin side of things was choking.
