How can I determine if the theme I am using is version 1.0 or 2.0?

If you’re unsure whether your Shopify theme is an Online Store 2.0 theme or a 1.0 (Vintage) theme, you can easily check this by following the steps below.

Steps to Check Your Theme Version

Go to your Shopify Admin.
Navigate to Online Store → Themes.
Locate your current (published) theme.
Click the three-dot (⋯) icon next to the theme and select Edit code.
In the Templates folder, look for a file named product.json.

How to Interpret the Result

If product.json exists
Your theme is an Online Store 2.0 theme and is fully compatible with the Fether app.
If product.json does not exist
Your theme is a 1.0 (Vintage) theme. Unfortunately, 1.0 themes are not supported by Fether at this time.

Why Theme Version Matters

Fether relies on Shopify’s Theme App Extension framework, which is only supported by Online Store 2.0 themes. Due to Shopify platform limitations, apps like Fether cannot function properly on 1.0 themes.

If your store is currently using a 1.0 theme, we recommend upgrading to a 2.0 theme to ensure compatibility and access to all Fether features.
