Why am I not on www.?

I installed my zen cart using CPanel Fantastico through my provider JustHost. I had an existing site https://www.midwestnotebooks.com built on HTML when I installed the zen cart.

I can go to http://www.midwestnotebooks.com and view the site but when I click on any link on the page it reverts to http://midwestnotebooks.com

Is this normal? Any ill effects? I seem to have lost of traffic data on google analytics.

If you change the HTTP_SERVER and HTTPS_SERVER settings in your includes/configure.php file to read "http://www.midwestnotebooks.com" this will sort itself out.

Thanks!

That worked! Changed permission to write to configure.php and updated. Changed permission back to read only.

That should definately solve my Analytics issue.

On a side note, I put my Analytics code in Google Checkout. Is this sufficent to get the traffic reports or does Checkout use it for some other reason?

It threw me a curve ball. I could change permission in Dreamweaver but could not change it back. Said does not work on some servers, logged into CPanel and changed permission correctly.
