I see an error that says "Unable to Show Theme Header and Footer"

This error shows when the Replo editor is not able to show a preview of your Shopify store's theme layout.

Generally, the Replo editor will load your theme in order to show you previews of headers, footers, blog post layouts, etc. However, some themes rely on dynamic layout positioning code, animations, or Javascript that Replo can't control. In these cases, Replo won't be able to show a preview of your theme header/footer or layouts in the editor, but the layout and header/footer visibility will still be applied when your page is published.

If you think this error is unexpected you can always reach out to Replo support — see 📄 Getting Help - How can I contact Replo support?
