A module works in the admin test and fails for a customer

Zen cart programming starts with a real fault on the site you have. The usual one is this: a module works in the admin test and fails for a customer.

What is usually wrong

• A module works in the admin test and fails for a customer
• An order email goes out blank
• Product extra fields show in the admin and not on the product page
• Checkout stops on shipping or payment

What we look at

We read the Zen Cart version and the module that failed. A new theme does not repair a shipping quote that never returns.

• Zen Cart version and PHP version
• Whether the database matches the files after a partial upgrade
• A test product and a test customer
• Template overrides that replace core files

How the job starts

Development on a live system is a change with a before and an after. We say which file, module, or query we are touching, and what the page should do when we are done.

If the feature does not exist yet, we still start from the page that needs it. We do not rebuild the parts that already work just to have a clean repository.

Most of this work happens on the site you already have. You do not need to be in Toronto. The first step is still a look at the live page.

Call 905-426-1784. We look at the site and tell you what the work is before it starts. The service page for this is Zen Cart help.
