What's happening
If a standard pass is added to the cart and this message is shown at online checkout:
“We are sorry but a technical error has occurred which unfortunately requires you to start again (409).”
… it usually means the standard pass has been set up with a fixed quantity and is also linked to a resource.
Why it happens
Standard passes are often used for flexible entry — guests can arrive any time during the day.
When these passes are linked to a resource, they should be set to Unlimited to ensure availability is managed by the resource’s capacity, not a fixed ticket count.
If a quantity limit is applied and the pass is linked to a resource, it creates a conflict — leading to the 409 error at checkout.
How to fix it
- From Venue Manager, go to Products > All Products.
- Select the standard pass you want to update.
- From Standard pass details, select one of your variations.
- Check the box for Unlimited.
- Select Save to save your variation changes.
- Repeat this process for any other variations that may need to be updated.
- Then, Save the product.
Check it's working
Confirm the Standard pass is now available to purchase from the online checkout:
-
Go to Apps > Progressive checkout > All checkouts.
- Open the checkout URL where guests can purchase the standard pass.
- Add the Standard pass to the cart and confirm the notification no longer appears.
