I am having real problems trying to find out why my site is using a mix of secure and non-secure links. For example, the website is https://www.greenfieldit.com.au/shop. When you view the page source, there is a mix of links with http:// and https://, I cannot seem to find out why.

I have searched for absolute URL's on my site and cannot find any. Also, the store configure.php file includes the following...

PHP Code:
  
 define
('HTTP_SERVER''http://www.greenfieldit.com.au');
  
define('HTTPS_SERVER''https://www.greenfieldit.com.au');

  
// 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''/shop/');

  //the following path is a COMPLETE path to your Zen Cart files. eg: /var/www/vhost/accountname/public_html/store/
