Easy Optimizer – Speed, Cache, Unused CSS, Delay JS, Lazy Load, LCP & Core Web Vitals

Changelog

2.4.0

• New: Dashboard speed test — Google PageSpeed score before vs after, mobile and desktop, with Core Web Vitals.
• New: Backend Analyzer — find slow plugins, themes and database queries by profiling any page or admin URL.
• Fix: admin toolbar menu missing in wp-admin (Clear All Cache / Used CSS / LCP) — restored.
• Fix: blank admin panel when another plugin loads React (“Identifier ‘React’ has already been declared”).
• Fix: autoload options disabled on WordPress 6.6+ now show correctly with a working Enable button.
• New: optional Cloudways hosting recommendation when a slow score is detected on non-Cloudways sites.
• Fix: cookie-keyed cache variants (currency/language switchers) could be served the wrong variant in .htaccess mode — rewrite serving now auto-falls back to drop-in/PHP when variant cookies are registered
• Fix: page-builder template and reusable-block saves no longer trigger repeated full cache purges — purges are debounced and coalesced (max one per minute, nothing skipped)
• Fix: settings import now runs through the full save pipeline (drop-in, .htaccess and cache are refreshed immediately)
• Fix: permalinks containing “.xml”/”.txt” in the slug were wrongly excluded from drop-in cache serving
• Fix: HEAD requests are now served from cache in PHP mode (headers only) instead of booting WordPress
• Fix: cached page counter self-seeds and falls back to a real scan on fresh installs
• Fix: theme-switch now also clears remote-CSS fetch transients
• Fix: uninstall cleans up site transients and no longer deletes data by default on installs that never saved settings
• New: per-site drop-in configuration on multisite — every network site is served with its own settings
• New: unused-asset garbage collection — minified/inline/used-CSS files not referenced by any render in 30 days are removed daily
• New: Cloudflare per-URL purges are batched, deduplicated and capped per request (large bursts escalate to one zone purge)
• Improved: database autoload toggle uses the WordPress 6.4+ core API and recognises WP 6.6+ autoload values
• Improved: cache engine split into focused modules with shared serve logic between runtime and drop-in; classmap autoloader added
• Multisite: .htaccess rewrite mode safely disabled (shared root file); full-clear site scan is now cached

2.3.2

Fixed – Astra: .ast-header-break-point styles are now excluded from desktop Used CSS (kept on mobile; skipped when Separate Mobile Cache is off).
Fixed – Queue table bloat on large sites — failed and orphaned rows are now auto-cleaned and disk space reclaimed, preventing unbounded growth.
Improved – Added a daily queue cleanup, a cleanup index, and a one-time table optimization on upgrade.
Improved – Cache invalidation overhaul. Editing a post now clears just the affected URLs (the post, its archives, author, date and taxonomy pages, with pagination) instead of needing a full flush, and a changed slug also clears the old URL.
Improved – Comment actions (new comment, approve, spam, edit) now clear only that post’s page instead of the whole cache.
Improved – Taxonomy term, author profile and media edits now trigger targeted, lightweight cache clears.
Improved – Multisite: clearing the cache now affects only the current site, never the rest of the network.
Improved – WooCommerce: cart, checkout and account pages are reliably kept out of the cache, including custom or translated page slugs.
Improved – WooCommerce: multi-currency stores (CURCY, WPML/WCML, Aelia, WOOCS) now cache a correct copy per selected currency.
Improved – Simplified the admin-bar menu to three focused actions: Clear Page Cache, Clear Used CSS and Clear LCP Images for the current page.
Improved – Minified the link-prefetch and LCP beacon scripts for a smaller front-end footprint.

New – Added a “noojs” body class (removed automatically once JavaScript runs) so themes can style the pre-JS / delayed-JS state. Hardened against themes and plugins with duplicate or malformed output.

Fixed – HEAD requests no longer return the page body on a cache hit.
Fixed – Removed unused/dead code in the WooCommerce and caching layers.

2.3.0

• Added: first-run setup wizard. On a new install, nothing is enabled until you choose one of three presets — Safe (cache, browser caching, gzip, font-display swap, LCP preload, lazy load, cache preload, moderate prefetch), Balanced (adds Remove Unused CSS in Async mode, Delay JS with jQuery excluded, and add-missing-image-dimensions), or Maximum (Used CSS in Delay mode, Delay JS including jQuery, lazy-load fonts). Existing sites keep their settings and are not shown the wizard.
• Added: Minify CSS and Minify JavaScript. Each minifies local files only, caches the result on disk, and processes a given file just once, so the per-request cost stays minimal. Already-minified files are skipped, relative url()/@import paths inside CSS are rewritten so assets keep resolving, and the Delay-JS loader and lazy-load runtime are never touched. Minify reuses the existing Exclude Stylesheets / Exclude Scripts fields and works independently of Remove Unused CSS and Delay JS.
• Added: Safe Mode button (Settings tab) that instantly reverts to the conservative Safe preset and turns off the riskier features — a one-click known-good baseline for troubleshooting.
• Added: query-string debug switches. Append ?nooptimize, ?nocache, ?nodelayjs, or ?norucss to any front-end URL to disable that feature for a single request without changing settings (the switched request is never cached, so you always see fresh output). Instructions are shown on the Settings tab.
• Fixed: Remove Unused CSS now has a fail-safe — original stylesheets are only delayed/async’d/removed after a valid Used CSS file has been generated and passes a confidence check (minimum size, real rule blocks, at least one stylesheet processed). If generation comes up empty or low-confidence, the page is served with its original styling untouched and is not cached, preventing rare unstyled-page output.
• Changed: the diagnostics opt-in is now requested in the setup wizard (and remains toggleable later), so the separate opt-in admin notice has been removed.

2.2.2

• Fixed: cached page count could repeatedly drop back to near-zero while the preload queue stayed at hundreds/thousands of URLs. Recording a page’s LCP element no longer wipes the entire cache and restarts the whole preload crawl — it now refreshes only the affected page. This removes a self-perpetuating clear → re-preload loop that prevented the cache from ever filling on some sites.
• Fixed: lazily-expired cached pages now adjust the page counter correctly, so the dashboard count no longer drifts upward after TTL expiry.
• Improved: cached files are written atomically (temporary file + rename) so a concurrent visitor can never receive a half-written page under load.
• Improved: Apache-served cache files always send a single Vary: Accept-Encoding.
• Added: Debug Log now records excessive cache purges, stalled or looping preload queues, the origin of every full cache clear, and cache-write failures — making invalidation loops easy to spot.
• Added: Settings → Debug Logging lets you enable/disable error and warning logging independently. Error logging is on by default.
• Fixed: the Debug Log is no longer deleted when you clear the cache. It now lives in wp-content/cache/easyopt-logs/ (outside the cache directory); any existing log is migrated automatically on update.
• Improved: preload and serving warnings are far less noisy — the preload “queue growing” and “stalled” warnings now only fire on a genuine problem (e.g. a real invalidation loop, or an actively-running queue that isn’t progressing), not during a normal preload start or behind a CDN.
• Performance: no feature changes; the loop fix substantially lowers CPU and disk usage on busy and low-resource/shared hosting.

2.2.1

• Fixed: HTTP 500 on some Apache/LiteSpeed servers after writing .htaccess. Removed the obsolete Internet Explorer / Netscape 4 BrowserMatch gzip directives, which are rejected by the LiteSpeed/OpenLiteSpeed config parser. Gzip and Brotli compression are unchanged — the exact same content types are still compressed.
• Fixed: AddOutputFilterByType (Gzip/Brotli) is now wrapped in <IfModule mod_filter.c>, the correct module on Apache 2.4, instead of mod_deflate.c.
• Fixed: Cache-directory responses no longer send Content-Encoding: gzip on uncompressed files — the gzip headers are now scoped to the .html_gzip cache files only, preventing rare decode errors for clients that don’t accept gzip.
• New: Per-server safety probe. Before writing to the live .htaccess, risky rule classes (Gzip directives and Options -Indexes) are now tested in an isolated throwaway directory. Any rule the server can’t parse is skipped automatically so it can never 500 the site — the page-cache rewrite, Expires headers and everything else still apply.
• New: Options -Indexes is only emitted after passing its sandbox probe (it 500s where AllowOverride forbids it). A blank index.html is written to the cache directory as a universal directory-listing safeguard.
• New: OpenLiteSpeed is now detected and the Gzip block is skipped on it (the server compresses natively), matching how other top performance plugins behave.
• Improved: The loopback validation no longer treats a blocked loopback as success. If it can’t confirm the write, an admin notice is shown instead of silently continuing.
• New filters: easyopt_htaccess_gzip block output and easyopt_probe_unverified_default / easyopt_probe_unverified_ok for hosts that block loopback HTTP.

2.2.0

• New: Auto-detect and purge server-level caches across major hosting providers (Cloudways, Kinsta, WP Engine, SiteGround, Pantheon, Flywheel, Pressable, and more).
• New: Dashboard card showing detected server cache layers.
• New: Direct Varnish HTTP PURGE fallback for Cloudways when Breeze is not installed.
• Improved: Server cache purge is rate-limited to once per request and uses non-blocking HTTP.
• Improved: Full server purge only on explicit cache clear — post saves only purge the changed URL.
• Improved: Apache htacess creation.
• Added support for Pantheon, Flywheel, Pressable, Closte, and Convesio hosting environments.
