How do I update WooCommerce template files in my theme? [closed]

The outdated files are in your theme’s woocommerce folder (unless the theme has stored them elsewhere, but that is the default). You don’t need this folder per se and can rename it (which is the more temporary way than flat-out deleting it) and WooCommerce will work. If you purchased the theme you could also contact their support and see about purchasing an upgrade because if the theme has been updated for compatibility.

If there were important customizations in your templates then begins the super-fun job of comparing the old templates to the new ones (which are in the plugin WooCommerce’s templates folder).

When WooCommerce 2.0 was released I had to save a client site whose checkout process was totally broken by outdated theme templates. The original theme people had copied all of the WooCommerce templates in lieu of just the ones they wanted to modify. In the end I removed all but maybe 3 of the override templates.
