SSL Error on Checkout - "www" dropped from URL by my cart

Hi: I've had the SSL installed on our website...
http://blinddogcoffee.com...and looks like https is working ok...
https://blinddogcoffee.com

The store is locatetd inside the zen directory...
http://blinddogcoffee.com/zen

**Problem: **When I click on "Go To Checkout" the "www" is dropped and my browser shows a Certificate Error. Example
https://blinddogcoffee.com/zen/index.php?main_page=login

If I add "www" manually in the browser it looks fine
https://www.blinddogcoffee.com/zen/index.php?main_page=login

Question: Have I done something wrong on my install? Or, did our hosting company install the SSL wrong? Here's my include config code for both files.

INCLUDE FILE CODE:
define('HTTP_SERVER', 'http://blinddogcoffee.com');
define('HTTPS_SERVER', 'https://blinddogcoffee.com');

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

ADMIN INCLUDE CODE:
define('HTTP_SERVER', 'http://blinddogcoffee.com');
define('HTTPS_SERVER', 'https://blinddogcoffee.com');
define('HTTP_CATALOG_SERVER', 'http://blinddogcoffee.com');
define('HTTPS_CATALOG_SERVER', 'https://blinddogcoffee.com');

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

If your certificate requires the "www" part, then add it to your URLs in your configure.php files.
Your URLs need to match your certificate.

Well its not dropping the www by accident itws following your commands

This

INCLUDE FILE CODE:
define('HTTP_SERVER', 'http://blinddogcoffee.com');
define('HTTPS_SERVER', 'https://blinddogcoffee.com');

needs to be

INCLUDE FILE CODE:
define('HTTP_SERVER', 'http://www.blinddogcoffee.com');
define('HTTPS_SERVER', 'https://www.blinddogcoffee.com');

You created the ssl with the www intact, however you are telling zen to NOT use the www

this should take good care of ya

**Thanks very much Doc! **It looks like it's working now! -Mitch
