Cobalt Checkout Diagnostics for WooCommerce is an admin diagnostic plugin. A shop manager with manage_woocommerce<\/code> can run local, read-only<\/strong> checks to see whether cart and checkout look configured and renderable on this site.<\/p>\n\n

It does not<\/strong> process payments, place orders, or watch the store from the public internet.<\/p>\n\n

Video overview<\/h4>\n\n

Product truth<\/h4>\n\n

Local checks do not prove that a real external customer can complete payment. This plugin must never be described as a live checkout or payment monitor.<\/p>\n\n

What this version does<\/h4>\n\n
    \n
  • Support-matrix guard for PHP 8.2+, WordPress 6.9+, and WooCommerce 10.8+<\/li>\n
  • Manual diagnostic run from WooCommerce \u2192 Checkout Diagnostics<\/strong><\/li>\n
  • Read-only checks for versions, HTTPS, permalinks, cart\/checkout pages, block vs classic type, catalog, enabled payment gateway ids, shipping, HPOS vs posts storage, WP-Cron, and Action Scheduler<\/li>\n
  • Safe loopback cart probe and checkout-render probe (GET to this site\u2019s assigned URLs only)<\/li>\n
  • Configuration snapshots and a changes check against the previous run<\/li>\n
  • Run history on this site, grouped results, evidence, and allowlisted remediation links<\/li>\n
  • Optional scheduled runs (Action Scheduler when ready, otherwise WP-Cron)<\/li>\n
  • Optional operator incident email to the site admin address (off by default)<\/li>\n<\/ul>\n\n

    What this version does not do<\/h4>\n\n
      \n
    • Charge a gateway, create orders, change stock, send customer mail, or trigger fulfilment<\/li>\n
    • Expose a public REST API<\/li>\n
    • Accept arbitrary probe URLs<\/li>\n
    • Claim that a real customer can complete payment<\/li>\n<\/ul>\n\n

      Requirements<\/h4>\n\n
        \n
      • PHP 8.2+ (8.3 or 8.4 recommended)<\/li>\n
      • WordPress 6.9+ (tested up to 7.1)<\/li>\n
      • WooCommerce 10.8+ (tested up to 11.0)<\/li>\n
      • Block Cart\/Checkout, classic shortcodes, mixed setups, and HPOS or posts storage are all in scope<\/li>\n<\/ul>\n\n

        Limitations<\/h3>\n\n
          \n
        • Local checks do not prove that a real external customer can complete payment.<\/li>\n
        • Probes are loopback HTTP GETs to this site\u2019s cart and checkout permalinks. They do not POST checkout, call process_payment<\/code>, or hit Store API write endpoints.<\/li>\n
        • Probe timeouts are capped (default 10 seconds, maximum 15). TLS verification is never disabled.<\/li>\n
        • Scheduled WP-Cron runs are approximate. Action Scheduler jobs are not unscheduled during uninstall if Action Scheduler has not initialized yet; leftover actions then fire a no-op hook.<\/li>\n
        • Incident email is not sent on every run. Fail and warning are both incidents. Recipients cannot be typed in the UI.<\/li>\n
        • This plugin has no REST API.<\/li>\n<\/ul>\n\n\n
            \n
          1. Upload the cobalt-checkout-diagnostics<\/code> folder to \/wp-content\/plugins\/<\/code>, or install the zip via Plugins \u2192 Add New \u2192 Upload Plugin<\/strong>.<\/li>\n
          2. Activate WooCommerce<\/strong> first, then activate Cobalt Checkout Diagnostics for WooCommerce<\/strong>.<\/li>\n
          3. Open WooCommerce \u2192 Checkout Diagnostics<\/strong> and run checks.<\/li>\n
          4. Optionally enable scheduled runs and operator incident email in the settings on that screen.<\/li>\n<\/ol>\n\n

            If WooCommerce is missing or too old, the plugin shows an admin error and does not register the diagnostic screen.<\/p>\n\n\n

            \n

            Can this tell me that customers can pay?<\/h3><\/dt>\n

            No. Local diagnostics do not prove that a real external customer can complete payment.<\/p><\/dd>\n

            Does a run create a test order?<\/h3><\/dt>\n

            No. Checks are read-only. They do not create orders, change stock, send customer mail, or charge a gateway.<\/p><\/dd>\n

            Who can run checks?<\/h3><\/dt>\n

            Users with the manage_woocommerce<\/code> capability. State-changing forms also require a WordPress nonce.<\/p><\/dd>\n

            Does the plugin send data off-site?<\/h3><\/dt>\n

            No. History stays in this WordPress database. Optional incident emails use WordPress mail to the site admin address (and any extra addresses a developer adds with a filter). There is no telemetry.<\/p><\/dd>\n

            Are scheduled runs exact?<\/h3><\/dt>\n

            When WooCommerce has initialized Action Scheduler, recurring jobs use that. Otherwise WP-Cron is the fallback. WP-Cron timing is approximate and depends on site traffic.<\/p><\/dd>\n

            Does uninstall delete my diagnostic history?<\/h3><\/dt>\n

            Scheduled jobs are always cleared. Tables and options are deleted only if you enabled Delete plugin data on uninstall<\/strong> before removing the plugin.<\/p><\/dd>\n\n<\/dl>\n\n\n
