In zen cart how can I enable/disable the "New Products for [insert month]" or Featured/Special/Upcoming Products sections.

There is a "New Products for [insert month]" section on several pages, including Home Page, New-Products page, All-Products Page, (empty)Shopping Cart page, etc.  These sections are called "centerboxes".

There are several "sets" of settings for the Centerboxes.

When you go to Admin->Configuration->Index Listing, you will see options like:

• Show New Products on Main Page
• Show Featured Products on Main Page
• Show Special Products on Main Page
• Show Upcoming Products on Main Page

- Note: the values you set are the Sort Order of the Centerboxes ...
- Turn OFF by setting to 0 all of the ones you do NOT want to see displayed ...

The same is true on New Listing / Featured Listing / All Listing / Index Listing

For setting up the Centerboxes of the Empty Shopping Cart, use the settings on the Admin->Configuration->Stock, you will see the settings for:

• Show New Products on Main Page
• Show Featured Products on Main Page
• Show Special Products on Main Page
• Show Upcoming Products on Main Page
