When you purchase one of our add-ons or GP Premium, you may assume that it’s a theme which you need to install via the “Themes” area of your WordPress Dashboard. Doing so will result in an error telling you that the theme is missing the style.css stylesheet.

This means you need to upload them through the “Plugins” area of the Dashboard.
