Choose the symptom first. A missing widget, wrong cart contents, and a wrong price need different checks.
No bundle on the product page
Status, targeting, and theme setup below.
Bundle shows, but the cart is wrong
Offer contents, variants, and the add-to-cart button.
Cart items are right, but the price differs
Discount and checkout checks.
1. Check status and targeting
Open Bundles. Confirm the offer is published and active and your plan permits publishing.
Check the actual product or collection and schedule against the page you are testing. If market visibility is available, also check the customer’s market.
If publishing failed, correct the specific error before retrying.
Choose the products that display the bundle and check its schedule.
2. Check the theme
Open the theme and product template customers are using.
Confirm the Sternify bundle block is present and the Sternify app embed is enabled.
Save, refresh the product page, and try again.
If the wrong items reach the cart
Empty the test cart, choose one offer and variant combination, and use the normal product add-to-cart button. Compare the result with the offer’s products, quantities, defaults, and gifts. Then test any sticky or quick-buy button separately.
If the issue only occurs in UpCart, follow the UpCart compatibility steps.
Still stuck? Send the product URL, offer name, selected variants, and the exact button used. Include expected versus actual cart items or price. These details identify which step needs fixing.
