Before you can start using elements in PageFly, you must manually add the Okendo metafields in theme.pagefly.liquid.

You need to add these 2 lines of code before </head> in file theme.liquid and theme.pagefly.liquid:

{{ shop.metafields.okendo.ReviewsWidgetStyleTag }}

{{ shop.metafields.okendo.StyleCustomizations }}

For more information about creating elements in PageFly, see this article in PageFly's Help Center.
