原文外掛簡介
A general-purpose cache-clearing plugin for any WordPress site. It works identically regardless of which theme or page builder you use — Divi, Elementor, Gutenberg, a classic theme, all of it — because it hooks into WordPress’s own standard save/activate/deactivate events, not anything builder-specific.
What it does, on any site:
Instantly clears every relevant cache the moment you save a page or post — the block editor, the Customizer, Divi Builder, or any other editor — no manual reload required.
Runs a lightweight background job on a custom schedule (1, 3, 5, 10, 20, 30, or 60 minutes — your choice) to keep object cache and expired transients tidy, without touching site performance.
Also clears automatically whenever any plugin on the site is activated, deactivated, or deleted.
Detects and flushes WP Rocket, W3 Total Cache, WP Super Cache, LiteSpeed Cache, SiteGround Optimizer, and Autoptimize automatically if they’re active — no extra configuration.
Optional built-in Public/Private page caching, with a true early-bypass mode that serves cached pages before WordPress even loads.
Optional persistent object cache — APCu, Redis, Memcached, or a zero-dependency File-based fallback — auto-detected and auto-selected, no manual backend picking or connection testing required.
Automatically refreshes its own page-cache and object-cache files whenever the plugin itself is updated, so bug fixes and speed improvements actually take effect instead of a stale copy silently running forever.
Optional Database Optimization — clean post revisions, trashed posts, spam comments, and expired transients, plus a table-optimization pass. Off by default, only runs when explicitly requested.
Ships with a modern React-based settings panel (built on WordPress’s own bundled React — no separate build step, no bloat) with live toast notifications and a real-time countdown to the next scheduled clear.
Why “light” vs “full” clearing matters
Earlier cache-clearing approaches run a full clear (OPcache reset, full cache-plugin flush, filesystem walks) on every timer tick — which can itself slow a site down if it happens too often. This plugin splits the work:
Light clear (runs on your background schedule): only the cache types you’ve switched on. Cheap, frequent, invisible.
Full clear (runs only when something actually changed — a save, manual click, theme switch, or plugin update): everything, including OPcache and third-party cache plugin flushes.
Automatic bonus support for Divi
If Divi happens to be active on the site, the plugin detects it automatically and adds continuous purging of Divi’s et-cache directory — a common source of “I edited it but nothing changed” on Divi sites — plus disabling Divi 4’s Static CSS File Generation setting so the folder is never created in the first place. On Divi 5 (which removed that setting entirely), the plugin purges the folder after every request instead. None of this runs, and none of it is needed, on a site that isn’t using Divi — the rest of the plugin works exactly the same either way.
