Fix Squarespace Checkout Errors
When your Squarespace checkout breaks, you need to fix it fast. Here's how to tackle the most common issues that stop customers buying from your site.
Start with the Browser
Most checkout problems come from browser issues. Before you panic, try these basic fixes:
- Check your browser is up to date. Old browsers cause all sorts of payment problems.
- Clear your browser cache or test in an incognito window. Cached data often conflicts with checkout updates.
- Turn off browser extensions. Ad blockers and privacy tools sometimes block payment scripts.
- Ask customers to check with their bank. Cards get declined for security reasons more often than you'd think.
Understanding Error Messages
Payment Processing Errors
"Unable to process payment" usually means your payment processor has disconnected. Here's how to fix it:
For Stripe or Squarespace Payments: Check your account is verified and active. If problems continue, disconnect and reconnect your processor in Settings > Payments.
For PayPal: Go to Settings > Payments, disconnect PayPal, then reconnect it. This refreshes the connection.
Domain and Order Completion Issues
Getting "We couldn't find the page you were looking for" after checkout means your domain isn't connected properly, even if payments went through.
Check your domain connection in Settings > Domains. Make sure it shows as "Connected".
Remember that domain changes take up to 72 hours to work everywhere. If you've just connected a domain, wait before testing again.
Resolving Other Issues
"Checkout is closed" appears when:
- No payment processor is connected
- Your currency isn't supported by your processor
- Your Squarespace plan doesn't include e-commerce features
Authentication messages happen because of Strong Customer Authentication rules in Europe. Customers need to verify payments with their bank using two-factor authentication.
Pixelhaze Tip: Test your checkout after every change you make. Don't wait for customers to find problems first.
FAQs
How can I resolve an 'Unable to process payment' error message on Squarespace?
Disconnect and reconnect your payment processor. This fixes most processing errors.
What should I do if customers receive a 'Payment for your order was declined' email?
Ask them to contact their bank. Most declines happen because of fraud protection, not your site.
Why is the shopping cart icon missing on my Squarespace website?
Check you're on a Commerce plan and have products published. The cart only appears when both are true.
Jargon Buster
Squarespace - Website builder that doesn't need coding skills
Browser cache - Stored website data that speeds up loading but sometimes causes conflicts
Payment processor - Service like Stripe or PayPal that handles your online payments
Domain - Your website address (like yoursite.com)
Express Checkout - Skip-the-cart feature that takes customers straight to payment
Wrap Up
Most Squarespace checkout issues come down to browser problems, disconnected payment processors, or domain connection issues. Work through these fixes in order, and test everything before calling it done.
If you're still stuck after trying these solutions, contact Squarespace support with specific error messages and screenshots. They can check your account settings directly.
