WooCommerce stores accumulate plugins fast, and it doesn’t take many before something starts breaking — a broken checkout, a duplicate discount, a payment gateway that silently stops working after an update. Finding out which plugin is responsible usually means deactivating things one at a time on your live site and hoping nothing goes wrong while you do it.
This plugin does two things instead:
1. An instant, zero-risk scan. Checks your active plugins against a list of documented, known conflicts (two caching plugins running together, two security firewalls, two SEO plugins fighting over schema markup, and specific vendor-documented pairs like WP Rocket + W3 Total Cache). This is read-only — it never changes anything on your site.
2. Safe test mode. When the scan isn’t enough and you need to actually isolate a plugin, safe test mode lets you do it without risk to your live store: the reduced plugin set is visible only in your own browser session, for up to two hours, and is never written to your site’s database. Every other visitor — and every other admin — keeps seeing your store exactly as it is. Close the tab, and it’s gone; it also expires automatically even if you don’t.
Nothing is ever written to disk or to your plugin list in the database, and every session expires on its own — there is no way to get stuck with plugins disabled and no way back.
General-purpose diagnostic tools treat every WordPress site the same. This one is scoped to WooCommerce stores on purpose: the conflict patterns it checks for, and the language it uses, are about protecting checkout and store functionality, not generic “something looks wrong” alerts.
