WordPress Checkout Issue

I'm experiencing an error during the checkout process on my WordPress site. The issue arises on the payment page, leading to the message "Error processing checkout. Please try again." Despite my attempts, I have been unable to resolve this.

I am using the Stripe payment gateway, and my WordPress and all plugins are up to date.

Ideal Skills:
- WordPress troubleshooting
- Stripe integration
- E-commerce experience

I need a freelancer who can diagnose and fix this issue as soon as possible. Thank you.
