After a LOT of messing around, I finally figured this out. It may not be a big deal for people who don't use a local dev site, but for those who do use WAMP server and have the same problem I was having, here is how I fixed it. Just be aware you may also have to tweak your httpd.conf file.
Before you proceed with what I'm going to suggest, PLEASE make copies of these 2 files: /your_store/includes/configure.php and /your_store/your_admin/includes/configure.php.
AND BACK UP YOUR DATABASE !!!!!! I take no responsibility for anything that goes awry with your installation. All I know is that this worked for me.
The problem had to do with 2 files in Zencart and also the MySQL database priveleges.
In /your_store/includes/configure.php, I made these 3 changes:
Changed define('HTTP_SERVER', 'http://localhost'); to define('HTTP_SERVER', 'http://192.168.x.x');
Changed define('HTTPS_SERVER', 'http://localhost'); to define('HTTPS_SERVER', 'http://192.168.x.x');
Changed define('DB_SERVER', 'localhost'); to define('DB_SERVER', '192.168.x.x');
In /your_store/your_admin/includes/configure.php, I made these 5 changes:
Changed define('HTTP_SERVER', 'http://localhost'); to define('HTTP_SERVER', 'http://192.168.x.x');
define('HTTPS_SERVER', 'https://localhost'); to define('HTTPS_SERVER', 'https://192.168.x.x');
define('HTTP_CATALOG_SERVER', 'http://localhost'); to define('HTTP_CATALOG_SERVER', 'http://192.168.x.x');
define('HTTPS_CATALOG_SERVER', 'https://localhost'); to define('HTTPS_CATALOG_SERVER', 'https://192.168.x.x');
define('DB_SERVER', 'localhost'); to define('DB_SERVER', '192.168.x.x');
In phpMyAdmin, selct your database and click the Privileges tab, then the Add User link. Fill in the Login Information field if you want to (I selected Any User from the dropdown). For the Host, select the option labelled as "Use Text Field" and type in your computer's LAN/IP address in the text box. Scroll down to the Global privileges form. Select the choose all link (or select specific ones you want to assign to this user). Click on Go button. When connecting to MySQL from your remote computer, use the details you just set up.
After doing all that, I restarted WAMP, put the server online (be careful with this unless you have a stupendous firewall running...as soon as you're done testing, be sure to take WAMP OFFLINE), and Anne's template now loads beautifully on all of my Android devices.
So...very long story short, Anne, you've done a fine job with your responsive templates....I applaud you and thank you profusely ! :clap: :clap: :bow:
