Checkout issues can arise due to plugin conflicts, outdated configurations, or caching. Here’s what you can try:

• Clear Cache: Clear both your server cache and browser cache to eliminate cached versions of the page causing the issue.
• Disable Plugins: Temporarily disable recently installed or updated plugins to identify if one is causing the problem.
• Check Payment Gateway Settings: Ensure your payment gateway credentials (e.g., Stripe or PayPal) are correct and up to date.
• Test Checkout: Use a test product and payment method to identify any specific errors during checkout.

If the issue persists, submit a support ticket with details of the problem, including any error messages, and we’ll investigate.
