I'm am using Zencart version 1.3.9h installed using godaddy's application installation in hosting controls. Run on Linux OS, with a template addon.
Godaddy said to use an .htaccess file to redirect site to show the "s" in the https://.
Code is as followed: in the .htaccess file located in root directory of site. This code is not from godaddy, i had to search it on the net.
*******
RewriteEngine On

RewriteCond %{SERVER_PORT} 80
RewriteRule ^(.*)$ https://www.greenletdesigns.com/$1 [R,L]
Is this correct?
********

After I installed SSL Certificate using these instructions from the Zen Cart Tutorial Site:
https://www.zen-cart.com/tutorials/index.php?article=14

Following these instructions from tutorial site, the customer was not able to log in, so i set the SSL codes after to 'true" the 2 configure.php in admin folder and includes folder:

from admin/includes/configure.php
define('HTTP_SERVER', 'http://greenletdesigns.com');
define('HTTPS_SERVER', 'https://greenletdesigns.com');
define('HTTP_CATALOG_SERVER', 'http://greenletdesigns.com');
define('HTTPS_CATALOG_SERVER', 'https://greenletdesigns.com');
define('ENABLE_SSL', 'true');

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

from /includes/configure.php
define('HTTP_SERVER', 'http://greenletdesigns.com');
define('HTTPS_SERVER', 'https://greenletdesigns.com');
define('ENABLE_SSL', 'true');

This worked and the customer was able to log-in.
New problem arised: I am not able to edit my products or any admin settings and have it save. After clicking the update button or save, it autoloads me back to the main admin controls page. I checked to see if the changes were save. NOTHING is SAVED. Products can be edited and added, but none of those changes were save.

I also tried removing the .htaccess file and left the 2 config files alone, Everything works fine. Only the checkout page has the "s" in the https://. I tried completely removing all codes changed and revert back to normal. Everything is fine. But i would like for all the pages to have the "s" in the https:// for customer security.

In addition, my Favicons don't appear anymore after SSL installation too. But it appears on my phone web browser. Following these instructions from Zen cart tutorial: https://www.zen-cart.com/tutorials/index.php?article=52

Please help with this issue. I've been searching my eyes out, i also called godaddy tech support. They said everything is working fine on their end. I've read through all the previous threads of this problem, but i still have not solved it.
