Hookniva Checkout Trace for WooCommerce helps you investigate missing shipping methods and payment gateways at checkout. Select products and a test shipping address, then compare your enabled settings with the methods WooCommerce actually returns.

Shipping methods not showing

Investigate WooCommerce shipping methods not showing for a specific product, country, state, postcode, or city. See the matched shipping zone and returned shipping rates. When no shipping options are available, compare the result with enabled methods and inspect code that can affect shipping availability.

Payment gateways not showing

Investigate WooCommerce payment gateways not showing under the selected cart and address conditions. Compare enabled payment methods with available gateways, and inspect callbacks that can filter the payment options.

Checkout troubleshooting for store owners and developers

Use the diagnostic to narrow down shipping and payment availability problems before changing store settings. The report shows current test results and code candidates to inspect; it does not guarantee the root cause or automatically fix checkout errors.

The plugin can:

Build an isolated diagnostic cart from selected products.
Recalculate shipping for a test country, state, postcode, and city.
Show the shipping zone and rates WooCommerce returns for that test package.
Show payment gateways WooCommerce considers available for the test cart.
Compare configured/enabled methods with methods actually available under the test conditions.
Inspect callbacks registered on key WooCommerce shipping and payment filters.
Show callback priority, source type, and a WordPress-relative source path when it can be identified.
Highlight external plugin, theme, MU-plugin, or custom-code callbacks as investigation candidates when checkout options disappear.

The plugin does not create orders, automatically disable plugins, or change shipping/payment/product settings. It runs normal WooCommerce cart and checkout calculation hooks during a diagnostic, so third-party callbacks registered on those hooks can execute.

A callback shown in a report is an investigation candidate, not proof that the callback caused the problem.

Checkout Blocks

This version diagnoses server-side WooCommerce shipping/payment availability and PHP hooks. Checkout Blocks also use Store API and browser-side JavaScript registration, so the plugin does not claim to trace every JavaScript-only decision made by a block-based checkout. Plugins that explicitly branch on front-end request context (for example is_checkout()) can also behave differently during an admin diagnostic request.

Privacy and external services

Hookniva Checkout Trace does not send diagnostic data to Hookniva or any external service. It does not create its own database tables and does not store diagnostic reports after the request finishes. It stores only the current administrator’s Korean/English UI preference in WordPress user meta so the selected plugin language is remembered. Korean interface translations are included with the plugin, so the Korean UI works without a separate language pack. Installed WordPress.org Korean language packs can also provide updated translations.
