If your online checkout will not load, shows a blank page or returns an error, work through the causes below in order. Each one has a quick check so you can find where the problem is.
A specific product shows an error or will not add
If the checkout loads but one product errors or is missing, the cause is usually that product's setup rather than the checkout itself. Check the matching guide:
Erreur lors du paiement lors de l'ajout d'un pass standard (couvre le message « erreur technique (409) »)
Pourquoi un pass standard n'est-il pas disponible dans ma commande en ligne ?
Pourquoi les modificateurs n'apparaissent-ils pas dans la commande en ligne ?
Guests cannot get past the payment step
If guests reach the payment screen but cannot complete the booking, this is a payment configuration issue rather than a loading issue. See Why can't my guests move past card payment details in the online checkout?
The checkout page will not load for a guest
If the page is blank, slow or will not load at all, the cause is usually the guest's browser or network. Ask the guest to:
Utilisez la dernière version de Google Chrome.
Videz le cache et les cookies du navigateur, puis rechargez la page.
Désactivez les extensions de navigateur et les bloqueurs de publicités, qui peuvent bloquer les scripts nécessaires à la commande.
Essayez un autre réseau ou appareil si la connexion est lente.
A checkout with no home page configured is not a fault. When no home page is set, the checkout opens on the product list instead.
ROLLER may be experiencing an outage
If the checkout is down for everyone, check the ROLLER status page at https://status.roller.app/ for any reported incident. You can subscribe there for updates. Once an incident is resolved, ask guests to clear their cache and cookies before trying again.
Still not working
If none of the above resolves it, contact your customer success manager or the support team with the checkout address, the device and browser used and a screenshot of the error.
