I've put a secure site Fusion 11 template on sale in the BeyondFusion store. $30 - with support included, of course.
The template is 3 pages - a login page, a secure page and a logged out page.
This template does NOT use the Fusion secure site component.
It uses PHP sessions, with PHP code embedded in the pages. Al included is one external php file used to connect to a MySQL database and another with instructions for creating a database to use with the security system.
