OnyxFlo Watchdog quietly monitors your WooCommerce orders in the background and takes snapshots at key points in the order lifecycle (checkout, thank you page, and status changes). It then compares those snapshots to detect suspicious changes or data inconsistencies.
OnyxFlo Watchdog uses a lightweight custom database table (<code>{prefix}onyxflo_watchdog_snapshots</code>) to store order snapshots. Uninstalling the plugin does not automatically delete existing snapshot data, so you can retain a historical audit log if needed.
Examples of what OnyxFlo Watchdog can help catch:
<ul>
<li>Orders where the cart or subtotal has changed between checkout and payment.</li>
<li>Orders that have been modified after payment but before fulfillment.</li>
<li>Data mismatches caused by buggy plugins, imports, or external integrations.</li>
</ul>
When a potential issue is found:
<ul>
<li>The order is changed to a custom status: Watchdog Flagged.</li>
<li>A clear warning notice appears on the order screen in wp-admin.</li>
<li>(Optional) An email alert can be sent to a configured address.</li>
<li>A snapshot history is stored so you can see what changed and when.</li>
</ul>
This plugin is aimed at stores that care about data integrity and want an extra layer of safety before orders are shipped or refunded.

OnyxFlo Watchdog for WooCommerce

Monitors WooCommerce orders for changes or mismatches and automatically flags suspicious orders to help ensure accuracy and prevent errors.

Log emails to the WordPress database for later analysis. Access is restricted to administrators, and emails with WordPress passwords are obfuscated for security / privacy. Useful for diagnosing lost email problems.
Use this plugin with <a href="https://shop.webaware.com.au/downloads/disable-emails/" rel="nofollow ugc">Disable Emails</a> to divert all WordPress emails into logs, especially handy for developers.
Logs are automatically purged after a defined period, set through a settings page in the WordPress admin. Setting the period to 0 prevents logs from being purged. Uninstalling the plugin purges all logs.

Log Emails

Thanks for a plguin, it was thoroughly coded and seems have all that I need.

Simple and useful plugin

Seriously, this plugin is so freakin' helpful. I work on a lot of sites that I have set up on my local development machine and don't have outgoing email set up on purpose. Only rarely do I need access to test those emails. But when I need it, it's typically urgent. This plugin has completely saved the day multiple times over the past month.

Thank you so much for the great work!

Only sad I didn't find this plugin sooner!

I've checked it's functionality and with first sight, it didn't contained vulnerable parts. Thank you.

compact and free from vulnerabilities
