Modify a zen-cart based website to make it fully controllable from "admin" panel.

I have a zencart based website and the home page is not editable from the admin panel.
This project is to modify the site so I can access the home page to change the images and content.
Site address is haywood-drinks.co.uk

I also have another zen-cart based site where I have added 2 products to the catalog and they don't appear visibly on the site. I need to get the URL of the pages involved so I can direct customers straight to the pages
Site address is haywoodproducts.com
