Use this page to find the fix fast. When a bundle does not appear on your storefront, it is almost always one of a few setup issues, not a problem with the bundle itself. Find the symptom that matches what you are seeing.
If the bundle's status is Draft, it will not appear on your store. Open the bundle in the Biscuits Bundles app, set it to Active, and save.
The Biscuits app embed has to be enabled in your theme for bundles to render. See How to activate the Biscuits Bundle App Embed in your theme.
The bundle builder is added to a product template as an app block. If your store uses more than one product template, the block has to be added to each template that has a bundle. See How to add Biscuits Bundle app to your theme and App Embed - Themes Guide.
App blocks require an Online Store 2.0 theme. See How to check if my theme is Online Store 2.0 and Does my theme have app blocks?.
This message means the block is on the page, but the bundle behind it needs attention. See 'Please check configuration in the app' Error.
Some themes or apps can stop the bundle rendering. See Known theme conflicts.
If you have more than one theme, or several product templates, confirm the app is installed where you need it. See Can I install Biscuits Bundles on multiple themes?.
Open the bundle in the Theme Editor to preview it in place. For more detail, see Why can't I see my bundles on the product page?. If you are still stuck, reach out with your store's .myshopify.com URL and the bundle's URL and we will take a look.
