  • Please be sure to review and apply the Site Security Recommendations to your site prior to taking your shop "live". If you are uncertain about how site security applies to you, talk to your web host to ensure that you have proper measures in place.


Zen Cart™ has had a major overhaul of the templating system for v1.3.x. As such, you have two options:
  • upgrade your existing template by applying the new stylesheet and moving a few lines of code around; or
  • the best way to have almost-tableless and much tidier template code, is to make a new template (based on template_default) and carefully re-apply your own customizations to the new template system.

For further information on template upgrading, see the forum discussion on this topic.
