CacheNova

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.
