Re: Making sure I protect everything!
What happens to stuff you do IN the zen cart admin (like ez pages, for example and your products for that matter) when you upgrade? I don't really understand how everything meshes yet so I don't really know "where" stuff like ez pages are stored.
All of your Data (products, customers, orders etc) is stored in the Database and is separate from the "files" - the files contain the templates and the code that gathers the information, makes the calculations and assembles the pages you see online.
Please do not PM for support issues: a private solution doesn't benefit the community.
Be careful with unsolicited advice via email or PM - Make sure the person you are talking to is a reliable source.
