Hi @esther0708,
Thanks for sharing that error! I tested payments on my side using Stripe setup, and everything processes fine without errors. A few questions that might help narrow it down:
- Check your WooCommerce → Settings → Payments → Stripe and verify that your API keys and Webhook URL are correct and properly configured.
- Do you have any caching plugins enabled? These can sometimes serve outdated or malformed scripts.
- When did the issue first appear? Did it coincide with any plugin updates, theme changes, or custom code edits?
- Have you checked your browser console during checkout to see if any JavaScript errors (in red) show up?
From the error message, it looks like Stripe’s form is receiving an invalid or malformed paymentMethodConfigurations object. That usually points to a JavaScript-side misconfiguration. This prevents customers from completing checkout.
Here are a few steps worth trying:
- Check the browser console and look for any red JS errors during checkout.
- Switch to Stripe test mode and see if the issue persists. This will help isolate whether it’s config-related or live API-related.
- Make sure WooCommerce, the Stripe plugin, and WordPress core are all up-to-date.
- Verify your Stripe configuration is complete and doesn’t have stray or deprecated keys.
- Disable caching temporarily: Clear any caches and see if that resolves it.
- Deactivate other plugins one by one to test for a possible clash: https://woocommerce.com/document/how-to-test-for-conflicts/
