If I built your site a few years ago using my Parallax for Writers theme, then you can’t run WooCommerce as-is. If you’d like to upgrade your theme for full support of selling direct, then this service is for you.

Parallax WooCommerce Upgrade
This service is only available to those who have it installed from years ago but doesn’t include populating products or store settings but videos are provided to guide you with WooCommerce.
