Troubleshooting

Start here when something is not behaving the way you expect. Each article below covers one symptom, with the checks in the order that resolves the most cases first.

• The subscribe widget is not showing on a product pageThe block renders nothing on a product with no selling plans, so this is almost always a product that is not attached to an offer yet.
• A new subscription did not appear under SubscribersContracts arrive by webhook within seconds, so a missing one usually means the shopper checked out one-time rather than choosing the subscribe option.
• A recurring payment failedNormal, and the app is built for it. Check dunning is on, where the subscription sits on the 1, 3, 5 and 7 day ladder, and whether the card still exists.
• Save offers are not showing when a subscriber cancelsThree causes: the cancel flow is switched off, every offer is still a draft, or the offer is set to fire for high-risk subscribers only.
• An AI assistant cannot connect, or its requests are refusedStart with the endpoint switch in Settings. After that it is usually an expired key, a reused confirmation link, or a cancel correctly waiting on the buyer.
• Churn scores are missing, or every subscriber looks the sameScores need history and refresh on the hourly pass. An empty at-risk list is a real answer, not a fault.
• A setting is disabled, or a change did not take effectPlan gates are re-checked on the server where a feature is used, so a stored value from a previous plan stops taking effect the moment the plan changes.
