Test Your WooCommerce Checkout Before Customers Discover the Problem

A checkout page can appear normal while an important payment gateway is missing, a Store API request is failing, a cache rule is affecting the session, or a recent update has changed the environment. These issues are often discovered only after customers abandon their carts or contact support.

WPStore+ Checkout Compatibility Tester gives store owners, developers, and support teams a structured way to inspect WooCommerce checkout readiness before a problem reaches customers. It combines server-side diagnostics with a browser-based Live Checkout Probe and compares current results with a known-good baseline.

The plugin is diagnostic and read-only. It does not submit the checkout form, create an order, authorize a payment, collect payment credentials, or automatically change WooCommerce settings.

Core Diagnostic Features

Complete Checkout Compatibility Diagnostics

Run a Full Server Scan to review the technical components that support the WooCommerce checkout flow:

• WooCommerce dependency and runtime environment

• Assigned Cart and Checkout pages

• Classic Checkout shortcode and Checkout Block detection

• Enabled and registered payment gateways

• AJAX, WordPress REST API, and WooCommerce Store API connectivity

• WooCommerce session-handler and browser-cookie support

• HTTPS and mixed-content signals

• Cart and Checkout response and cache-header signals

• HPOS status and compatibility declaration

• Checkout-, gateway-, currency-, session-, and cache-related extensions

Results are organized into PASS, WARNING, FAIL, and INFO groups so administrators can quickly identify what requires attention.

Administrator-Only Live Checkout Probe

The Live Checkout Probe observes the Checkout page under the current administrator browser session. It compares enabled gateways with the payment methods that are actually visible for the current cart, currency, address, shipping, account, and session conditions.

It supports both Classic Checkout and Checkout Blocks. The probe does not click Place order, submit customer information, or contact a payment gateway for authorization.

Gateway Intelligence & Conflict Tracking

Payment Gateway Visibility and Conflict Intelligence

An enabled gateway is not always available to the customer. Currency restrictions, country rules, cart conditions, shipping methods, custom callbacks, and gateway-rule extensions can all affect visibility.

Gateway Conflict Intelligence correlates enabled-versus-visible gateway results with:

• Privacy-safe availability-filter callback sources and priorities

• Active gateway-rule and currency-extension signals

• Store-versus-Probe currency differences

• Missing and unexpected gateway IDs

• NONE, LOW, MEDIUM, and HIGH confidence levels

It can observe Stripe, PayPal, bank transfer, cash on delivery, and other gateways registered with WooCommerce. The plugin reports correlation evidence for administrator review; it does not claim that a specific extension caused the issue and never executes availability callbacks itself.

Gateway Conflict Regression Tracking

Save a known-good baseline and track future changes in gateway conflict evidence. Version 1.11.0 can compare:

• Conflict status and confidence

• Missing gateway IDs

• Currency mismatch state

• Availability-filter count and source labels

• Candidate extension slugs

• Evidence signal keys

Differences are separated into regressions, warnings, improvements, and informational changes.

Baseline & Environment Tracking

Compatibility History and Known-Good Baseline

The plugin retains up to 20 compact compatibility snapshots. Administrators can select the current result or a previous History entry as the primary known-good baseline.

Future scans can identify:

• New failed checks

• New warnings

• Resolved checks

• Page, currency, gateway, runtime, and extension changes

• Live-visible gateway and browser-endpoint changes

• Gateway conflict regressions

• Checkout environment drift

History stores compact diagnostic observations only and does not contain orders, customer records, addresses, payment credentials, or cart product details.

Checkout Environment Drift Detection

Environment Drift Detection helps identify when the current checkout environment no longer matches the known-good baseline. It compares compact observations for:

• WordPress, WooCommerce, and PHP versions

• WordPress environment type

• Store and Live Probe currency

• Cart and Checkout page assignments, modes, and publication status

• Enabled payment gateways

• Live Probe Checkout mode

• Relevant extension slugs and versions

Drift is classified as Critical, Warning, Informational, Stable, or Pending. Critical changes are included in baseline regressions and can be detected by Scheduled Monitoring.

Scheduled Monitoring and Update-Aware Guard

Enable optional daily or weekly server-only monitoring with WP-Cron. The plugin can send alerts for FAIL results or for both FAIL and WARNING results.

Monitoring includes:

• Automatic comparison with the saved baseline

• Duplicate-alert suppression

• Optional recovery email

• Manual Run Monitor Now control

• Privacy-safe test email

• Optional delayed scan after completed WordPress core, plugin, or theme updates

• Compact sanitized update context

Scheduled monitoring does not run the browser Live Checkout Probe and does not modify the checkout environment.

Scenarios & Validation

Checkout Scenario Profiles and Gateway Matrix

Save up to 10 named checkout scenarios for conditions that matter to the store, such as:

• THB / Thailand / Standard cart

• USD / International customer

• Logged-in customer

• Specific shipping method

• Classic Checkout or Checkout Block

Each scenario can retain expected enabled and visible gateway IDs, currency, Checkout mode, observed cart-item count, and payment-requirement state. The plugin compares the current manually prepared context with each saved scenario without changing the cart, address, shipping method, account, currency, or gateway rules.

Validation Runs and Release Readiness

Create a named Validation Run before a release or major configuration change. Each saved scenario becomes a manual validation target with PASS, WARNING, FAIL, PENDING, STALE, or REMOVED status.

Release readiness is summarized as:

• READY — every target passes

• REVIEW — completed targets contain warnings

• BLOCKED — one or more completed targets fail

After WordPress core, plugin, or theme updates, the Revalidation Queue can mark saved scenarios as due for a fresh manual check.

Reports & Administration

Privacy-Safe TXT Compatibility Report

Download a structured TXT report for troubleshooting, documentation, or support handoff. Reports can include software versions, gateway IDs, diagnostic status, compact filter-source labels, monitoring state, conflict evidence, and environment drift.

Reports exclude customer data, addresses, payment credentials, full license keys, API secrets, package URLs, and absolute server paths.

WPStore+ License and Secure Updates

The plugin includes WPStore License SDK 2.2.1 for license activation, validation, site synchronization, offline grace cache, remote release metadata, and authenticated WordPress updates.

Version 1.11.0 does not restrict diagnostic features when a license is inactive. License activation is used for authenticated product updates and site synchronization.

Target Audience & Limitations

Built for Store Owners, Developers, and Support Teams

WPStore+ Checkout Compatibility Tester is suitable for:

• WooCommerce store owners preparing for launch

• Developers testing plugin or theme updates

• Support teams investigating missing payment gateways

• Agencies maintaining multiple checkout configurations

• Stores using Checkout Blocks, Classic Checkout, HPOS, currency extensions, or gateway rules

Important Limitation

A passing diagnostic report does not prove that a payment gateway can successfully authorize or capture a payment. Every gateway should still be tested using its official sandbox or test mode before production use.
