“Which plugin just broke my site?” — answered automatically.
Existing tools show you that an error occurred. Conflict Detective tells you which plugin caused it by correlating the plugin change timeline with the error log — and gives you a confidence score.
<h4>Features</h4>
Dashboard 
Live overview of your WordPress/PHP version, active plugins, active theme, memory limit, debug mode, recent changes, and latest errors — all on one screen.
Error Log Viewer 
Reads <code>debug.log</code> and the server PHP error log automatically. Each entry is attributed to the plugin that owns the file where the error occurred. Filter by Fatal / Warning / Notice / Deprecated.
Change History 
Full audit trail of every plugin activation, deactivation, update, and deletion — with exact timestamps and version diffs (e.g. <code>8.3.0 → 8.4.0</code>).
Health Scan 
On-demand scan that detects:
<ul>
<li>Duplicate plugin functionality (multiple SEO, caching, security, or backup plugins)</li>
<li>Known incompatibilities between specific plugin pairs</li>
<li>Outdated plugins (not updated in more than 2 years)</li>
<li>Missing theme files or a missing parent theme</li>
<li>PHP version, memory limit, and <code>max_execution_time</code> misconfigurations</li>
<li>Pending WordPress core updates</li>
</ul>
Conflict Scanner 
Automatically correlates plugin update timestamps with error spikes and reports a suspect plugin with a confidence percentage. Detected conflicts are stored in the database and can be marked as resolved with one click.
Safe Testing Mode 
Disable any plugin for your own admin session while visitors remain completely unaffected. Cookie-isolated — the live site is never touched.
Conflict Wizard 
Step-by-step guided diagnosis. Choose your symptom (white screen, login problem, WooCommerce issue, slow site, broken admin, front-end error, or other) and the wizard automatically analyses recent changes and errors to produce a tailored action plan.
Performance Monitor (new in 2.6.0) 
Tracks the estimated load time, memory delta, and database query count for every active plugin during the current page load. Results are color-coded as Fast / Slow / Heavy and refreshed on demand.
Cron Monitor (new in 2.6.0) 
Lists all scheduled WordPress Cron events with their next run time and interval. Overdue events are highlighted in red. Each event can be triggered manually via a “Run Now” button — validated against the live WP-Cron schedule before execution.
AJAX / REST Monitor (new in 2.6.0) 
Automatically logs slow AJAX and REST API calls (those taking more than 500 ms) to a dedicated database table. Filter by All / AJAX / REST / Slow to quickly identify bottleneck endpoints.
Plugin Interaction Map (new in 2.6.0) 
Visualises your plugins grouped into known ecosystem clusters (WooCommerce, Elementor, Yoast SEO, Jetpack, ACF, Gravity Forms, and more). Highlights declared plugin dependencies and shows active/inactive state at a glance. Plugins that don’t belong to a known ecosystem are listed separately as Standalone Plugins.

Filtering the activation of custom block plugins will allow you to speed up editing in the block editor and use different custom blocks that cause conflicts.
For example, if you use Jetpack plugin, but you don’t need Jetpack custom blocks and you want to clean up your editing screen.
