Troubleshooting checkout issues

Use this guide to troubleshoot problems you or your customers might see on your checkout page.

Check for browser issues first

If a customer is using a valid form of payment and can't check out, it’s likely because of an issue related to their browser. Unless they see one of the error messages listed below, ask your customer to try these troubleshooting steps:



Nächste Schritte

Unable to process payment

This means: There’s an issue with your Stripe or PayPal connection.

To resolve the issue: Ensure your Stripe account is verified, or Contact Stripe directly to ensure your account is fully set up. Refresh your connection by disconnecting and reconnecting Stripe (keep in mind, this may interrupt your active subscriptions).  If you use PayPal, disconnect and reconnect your account or contact PayPal directly.

Wir konnten die gesuchte Seite nicht finden.

This means: Your domain might not be connected properly. If this happens, the order was still processed, and you didn't lose the customer's payment.

To double-check that the order went through, look up their order in the Orders panel.

To resolve the issue: Ensure that your domain is correctly connected. If you recently connected your domain, it can take up to 72 hours to fully process.

Deine Bestellung kann aufgrund eines Problems mit der eingerichteten Zahlungsweise des Händlers nicht abgeschlossen werden. Bitte kontaktiere uns diesbezüglich.

This means: Your payment processor account may have been disconnected from Squarespace. You may also see this error in Test Mode. For your security, a payment processor will disconnect if:

  • There was an attempt to connect the same account to multiple sites.
  • If an authorization change occurred within your account (a password change, for example).

To resolve the issue, reconnect your payment processor account:

  1. Klicke im Hauptmenü auf E-Commerce und dann auf Zahlungen.
  2. Click Stripe or PayPal.
  3. Click Disconnect Stripe or Disconnect PayPal.
  4. Click Connect Stripe or Connect PayPal to reconnect.

For more help, contact Stripe or PayPal directly.

Payment for your order was declined (email)

This means: There was an unexpected error processing a payment after the customer saw the confirmation screen.

Next steps: The customer wasn’t charged. They should double-check their payment details and try again.

One or more items from your order aren’t available (email)

This means: There was an unexpected error processing a payment, and the product sold out before our system could make a second attempt.

Next steps: The customer wasn’t charged. They should go back to your store to purchase any available items.

Other issues

Authentifizierung fehlgeschlagen.

If the customer sees an Authentication failed message, this means their bank is located in the European Economic Area (EEA) and they need to authorize the purchase for Strong Customer Authentication (SCA). Ask your customer to retry the purchase and watch for a pop-up from the bank to authorize the payment. If they continue to have trouble, the customer will need to reach out to their bank for help. 

Country unavailable in drop-down menu

If the customer can't select their country in the shipping or billing information, you don’t have a shipping option for that country yet. For help adding a shipping rule, visit Setting country shipping rules.

Expired digital products

After a customer orders a digital product, they receive a link to download the product. The link will expire 24 hours after it's first clicked. You can resend the download link in the Email Notifications tab of their Order Summary.

Shopping cart icon is missing

In most templates, the icon appears when a customer adds a product to their cart. In some templates, it always displays.

If your shopping cart icon isn't showing, look for the following potential causes:

  1. Check that your site has at least one product on a Products Page.
  2. Ensure Express Checkout is disabled in Checkout Settings. Enabling Express Checkout disables the shopping cart.
  3. Check your Site Styles to see if your shopping cart is hidden.

The shopping cart can be hidden in these templates. Use the listed Site Styles tweak to show it again.

Tip: In version 7.1, enable the icon in the header to ensure it always displays.


Your store can’t accept real payments while it’s in test mode. To resolve this issue, disable test mode.

Customers can't add products to their carts

If a customer reaches out with trouble adding products to their cart, try these troubleshooting steps:

  • Ensure the products are set to visible, and that the Products Page is live.
  • Check for custom code in the product's Additional Information tab and your site's Header Code Injection field. Remove the code to see if that resolves the issue.
  • Ask your customer to ensure cookies are enabled on their browser. Here are instructions for Chrome, Firefox, and Safari.
