Link not showing up properly

Hi there, just installed and customized zencart, i notice that all my links work properly, except that instead of showing up as http://www.websitename.com, it just shows http://websitename.com. the "www" is missing. Any ideas to enlighten me? Thanks. :smile:

In your includes/configure.php you must have the
define('HTTP_SERVER', 'http://websitename.com');
should be:
define('HTTP_SERVER', 'http://www.websitename.com');
if you want the site to show the www.

thanks Marg, i just tried it, also changed the configure.php in admin/includes/configure.php as well. still the same. anywhere that i missed?

update! the moment i change it and upload the file, it changes back and remove my "www" in the configure.php file

Weird huh?
