Always try to remain with the latest solutions of templates, as it will save lots of trouble (especially when it comes to upgrade and you're about to do so on your live store after a almost successful testing). By downloading the latest template presentations - compatible for Zen Cart 1.3x - far less modifications would need to be done, from your end, as it would take far less time to assist users who requires technical assistance regarding template modifications. :wink2:
The best way to keep our stores updated, graphicly speaking, is to follow the DEV's example, from each Zen-Cart releases, from the includes/templates/template_default's entire folder.
As a second solution, to keep up-to-date, is to visit the template contributions section to see if new distributions has been published, and approved, by others. Questionning might also be a good idea before doing any installation over your test / live store in the mean time.
