How can I debug a custom payment method that disappears during checkout

Enable Debug Mode

1. Go to WooCommerce > Settings > Payments in your WordPress dashboard.
2. Find your custom payment method and click on "Manage".
3. Enable the "Debug mode" option and save changes.

This will activate debug logging for your payment method, allowing you to track any issues or errors that may be causing it to disappear.

Check the Logs

1. Go to WooCommerce > Status > Logs.
2. Find the log file for your payment method (e.g., "woocommerce-gateway-my-custom-method-debug.log").
3. Open the log file and look for any error messages or unexpected behavior related to your payment method.

The logs should provide valuable information about what's happening behind the scenes when your payment method is loaded on the checkout page.

Verify Compatibility

1. Make sure your payment method is compatible with the latest versions of WooCommerce and WordPress.
2. Check if there are any specific requirements or compatibility notes for using your payment method with WooCommerce blocks.
3. If necessary, update your payment method code to ensure it works seamlessly with the current versions of WooCommerce and the block framework.

Test with a Fresh Installation

1. Create a new WordPress site with the latest versions of WooCommerce and your theme.
2. Install your payment method plugin and activate it.
3. Go through the checkout process and observe if your payment method appears consistently.

Testing with a fresh installation can help you identify if the issue is specific to your site's configuration or if there's a problem with your payment method plugin itself.

Seek Support

If you're still unable to resolve the issue, consider seeking support from the plugin's developer or the WooCommerce community. They may be able to provide more specific guidance based on your payment method and the error messages you encounter in the logs.

By following these steps and thoroughly investigating the issue, you should be able to identify the root cause of your payment method disappearing during checkout when using WooCommerce blocks.
