SSL works but all links remain http not https

Got my SSL certificate today and my site now shows up at https://www.plugnplaypc.com/shoppingcart/ as it should.

However all of the links on the page--with the exception of the "Login" link at the top--remain http, not https.

I reverted to the default template in case I screwed something up in my custom template and I searched all my files for "src=http://" in case I hard coded something somewhere, but I found nothing.

I followed the directions for enabling SSL (https://www.zen-cart.com/tutorials/index.php?article=14) and did this:

Code:

---

/*************** NOTE: This file is similar, but DIFFERENT from the "admin" version of configure.php. ***********/
/***************      The 2 files should be kept separate and not used to overwrite each other.      ***********/

// 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://www.plugnplaypc.com');
  define('HTTPS_SERVER', 'https://www.plugnplaypc.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', '/shoppingcart/');
  define('DIR_WS_HTTPS_CATALOG', '/shoppingcart/');

Is there somewhere else I might have defined 'http' and need to change it to 'https'?

(Please forgive me if I missed the answer to this when I searched the forum and FAQ.)

Thank you.

ssl does not work on all pages...only those requiring input
of certain info i.e. login, cart etc

https is very slow, hence it is only used when it should be (on pages that involve transferring customer info etc)
