Shared SSL setup problem

[Mr.Pea]

I recently installed the latest edition of Zen Cart. For some reason Zen cart will not detect the shared SSL Certificate. Am I doing something wrong? I spoke with the hosting provider and they let me know the HTTPS is fine - the cart is just not redirecting to the https:// when the "Log-in" button is clicked on.

My includes>configure.php:
// Define the webserver and path parameters
// HTTP_SERVER is your Main webserver: eg-http://www.your_domain.com
// HTTPS_SERVER is your Secure webserver: eg-https://www.your_domain.com
define('HTTP_SERVER', 'http://mysite.com');
define('HTTPS_SERVER', 'https://mysite.com');

// Use secure webserver for checkout procedure?
define('ENABLE_SSL', 'true');

// NOTE: be sure to leave the trailing '/' at the end of these lines if you make changes!
// * DIR_WS_* = Webserver directories (virtual/URL)
// these paths are relative to top of your webspace ... (ie: under the public_html or httpdocs folder)
define('DIR_WS_CATALOG', '/mysite/');
define('DIR_WS_HTTPS_CATALOG', '/mysite/');
