I am having the same issue. My SSL-certificate is fine as far as i can tell: https://managertoolspublishing.com/test.php

So are the configure files, both in admin/includes and /includes:

Admin configure:

define('HTTP_SERVER', 'http://managertoolspublishing.com');
define('HTTPS_SERVER', 'https://managertoolspublishing.com');
define('HTTP_CATALOG_SERVER', 'http://managertoolspublishing.com');
define('HTTPS_CATALOG_SERVER', 'https://managertoolspublishing.com');

// Use secure webserver for catalog module and/or admin areas?
define('ENABLE_SSL_CATALOG', 'true');
define('ENABLE_SSL_ADMIN', 'true');
Include configure:

// 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://managertoolspublishing.com');
define('HTTPS_SERVER', 'https://managertoolspublishing.com');

// Use secure webserver for checkout procedure?
define('ENABLE_SSL', 'true');
What is causing the problem is the BASE HREF in html_header.php:

<base href="<?php echo (($request_type == 'SSL') ? HTTPS_SERVER . DIR_WS_HTTPS_CATALOG : HTTP_SERVER . DIR_WS_CATALOG ); ?>" />
If you look at the BASE HREF url in i.e.:

https://managertoolspublishing.com/s...ain_page=login

You will see that the BASE HREF is http, not https. Which makes all relative linked files: css, images cause a security warning. I haven't touched the code in html_header.php.

Any ideas? Of course security warnings will scare people away, so any help is greatly appreciated.
