Surfaces overlapping WordPress hooks, duplicate asset enqueues, priority extremes, and competing plugin functionality — the silent causes of erratic site behaviour.
Many of the most frustrating WordPress issues aren't caused by broken code — they're caused by two pieces of working code trying to do the same thing at the same time. Two caching plugins managing object cache simultaneously. Two plugins hooking the_content at priority 10 with conflicting output. The same JavaScript library enqueued twice by different plugins. The Conflict Detector identifies all four patterns — giving you a concrete list to investigate rather than a vague "WordPress plugin conflict" hunch.
Identifies WordPress hooks where multiple plugins have registered callbacks at the same priority, creating potential execution order conflicts. Flags hooks where combined callbacks from different plugins are likely to interfere with each other.
Finds JavaScript and CSS files being enqueued by more than one WordPress plugin under different handles. Loading the same library twice can cause JavaScript errors when a library re-initialises with conflicting settings from a second load.
Detects when multiple active WordPress plugins serve overlapping functionality — two caching plugins, two SEO plugins, two form plugins with conflicting shortcodes. Each conflict type is explained with the specific WordPress plugins involved.
Flags WordPress callbacks registered at unusually extreme priorities (e.g. PHP_INT_MAX or PHP_INT_MIN) — a pattern used by plugins trying to override each other's output and a reliable indicator of underlying WordPress conflict.
Not necessarily. A detected conflict means two WordPress plugins are competing for control of the same mechanism. Often both are working as designed — the problem is they weren't designed to coexist. Resolution usually involves configuring one to defer to the other, or choosing between them.
The module uses hook registration patterns, option prefix analysis, and a curated taxonomy of known WordPress plugin categories (caching, SEO, forms, security, etc.) to identify functional overlap. It's heuristic-based — useful as a starting point, not a definitive determination.
No. The Conflict Detector is purely diagnostic. Resolving WordPress plugin conflicts requires developer judgment. The module gives you the what and where — the how is up to you.
No. The WordPress Conflict Detector is a Pro-exclusive module.
Hook conflicts, duplicate WordPress assets, and competing plugins — a concrete list to investigate, not a hunch.
The Conflict Detector is included in every Pro plan alongside all seventeen diagnostic modules.
