It scans your active plugins and theme for the conflicts that quietly break sites, scores how well-maintained your plugins are, helps you pinpoint the culprit when something goes wrong, and lets you roll back a bad update with one click. Most conflict tools only help _after_ a site breaks. Guardian is built around three ideas: **prevent, detect, recover.** **What it detects** * Duplicate shortcodes registered by more than one plugin * Duplicate custom post types and taxonomies * Duplicate REST API routes * Duplicate AJAX actions * Duplicate script and stylesheet handles * Order-sensitive hook collisions (e.g. two plugins fighting over `the_content`,` template_redirect`, or WooCommerce checkout) * Cron events scheduled multiple times * Known incompatibilities — two caching plugins, two security/firewall plugins, two SEO plugins, and more * Duplicate WooCommerce payment gateways Every issue gets a **severity score (1–10)**, a plain-English explanation of what can go wrong, and a recommended fix. **Plugin Health Score** Guardian rates each active plugin out of 100 using public data from WordPress.org— last update date, active installs, ratings, support resolution rate, and compatibility with your WordPress and PHP versions — so you can spot abandoned or risky plugins. **Performance / Bloat scanner** See how much autoloaded data is loaded on every request, which plugins weigh the most, how many scheduled tasks are running, and your largest autoloaded options. **Binary-search troubleshooter** Disable plugins for _your session only_ to find a conflict fast. Visitors keep seeing the live site the whole time. Disable half, reload, narrow down — the classic bisection method, built in. **One-click rollback** When enabled, Guardian copies a plugin’s files and settings just before WordPress updates it. If an update breaks something, restore the previous version in one click. **Lightweight by design** Scans run as scheduled background jobs and are cached. Nothing heavy ever runs on a normal front-end page load. #### A note from TRUCE LABEL Guardian is built by [TRUCE LABEL](https://trucelabel.com). If you publish video, take a look at our **Video Ads Player** — a fast, VAST-ready WordPress video player with pre-roll, mid-roll, post-roll, and banner ads, so you can monetize the videos you already have.

It sends the slug of each active plugin in order to retrieve that plugin’s public maintenance data (last update, install count, ratings, tested-up-to, required PHP). No personal data or site data is sent. See the WordPress.org privacy policy: https://wordpress.org/about/privacy/. ## Installation 1. Go to **Plugins Add New** and search for “Guardian”, or upload the plugin ZIP. 2. Click **Install Now**, then **Activate**. 3. Open **Guardian** in the admin menu and click **Run a full scan**. 4. Review any conflicts, check plugin health, and adjust options under **Settings**. ## FAQ ### Will scanning slow down my site? No. Scans run on a schedule in the background and the results are cached. The front end is never used to run a scan. ### Does troubleshooting affect my visitors? No. Disabling plugins in the troubleshooter applies only to your own browser session, scoped by a secure cookie. Everyone else continues to see the site normally. ### What data does the plugin send anywhere? Only the Plugin Health feature makes an external request, and only to the public WordPress.org plugin information API — the same source the built-in Plugins screen uses — to read each plugin’s last-updated date, install count, ratings, and compatibility. No information about your site or its visitors is transmitted. ### Does it work with WooCommerce and multisite? Yes. Guardian includes WooCommerce-specific checks and is multisite aware. ### Is it really free? Yes. This plugin is fully functional and free under the GPL. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Guardian – Conflict Detector & Safe Updates” is open source software.
