Last updated on December 4, 2025

If your widget isn’t appearing on the product page, it could be due to several reasons. Please check the following:

  1. Confirm that the offer products are active and currently in stock.

  2. Make sure the BoostUp Upsell app embed is turned on in your theme. You can enable this through your theme customizer in the theme editor.

3. The “FBT List” app block is added in your theme. (2.0 theme).

4. For older themes that don’t support app blocks, you’ll need to manually adjust the placement.

5. If you continue to experience problems, reach out to our support team for complimentary setup help via chat, or book a Zoom session.
