CacheLoop – Simple Page Cache & Speed Optimization

Registo de alterações

1.0.20

• Added (Pro): “Select all” and “Deselect all” buttons in the Asset Manager CSS and JS lists.
• Fixed: cached pages were often served by the slower PHP fallback (response header X-CacheLoop-Cache: HIT-FALLBACK) instead of the fast early drop-in. This happened after wp cacheloop clear, after deactivating and reactivating the plugin with mobile/desktop cache split enabled, and on every page whose address contains special characters (e.g. ″ or accented letters). The drop-in now always finds the cached pages, and pages with different special characters in the address can no longer share the same cached copy.
• Fixed: after an update, CacheLoop could keep behaving as the previous version (no cache refresh after the update) until the settings were saved again.
• Fixed (Pro): “Disable Cart Fragments” and “Disable WooCommerce Assets” no longer break the header mini-cart or “Add to cart” buttons on pages that aren’t shop pages (for example a home page with a product grid). WooCommerce scripts are now removed only from pages that have neither a mini-cart nor add-to-cart buttons.
• Fixed (Pro): Delay JavaScript no longer causes “wp is not defined” errors, never delays cookie-consent banners (Complianz, Cookiebot, iubenda, CookieYes and others), and delayed scripts now run their “page loaded” code, which was previously skipped.
• Fixed (Pro): deferring JavaScript no longer causes “wp is not defined” errors: scripts that WordPress pairs with inline code, and the libraries they depend on, are left in their original order.
• Fixed (Pro): Combine CSS and Local Google Fonts could leave a page without its fonts or styles on hosts that don’t serve files from wp-content/cache/ (and always on Apache/LiteSpeed, where they were blocked). CacheLoop now opens only those asset folders on Apache/LiteSpeed, checks once that the files are reachable, and otherwise keeps the original stylesheets and fonts. Google Fonts written as //fonts.googleapis.com/... are now served locally too.
• Fixed: the PageSpeed recommendation for unoptimized images always said “CacheLoop does not compress or convert images”, even on CacheLoop Pro with Image Optimization enabled. It now reflects your actual setup: Pro users are told to enable Image Optimization or run “Optimize All” for existing uploads; only free users are pointed to an external image plugin.
• Fixed (Pro): with Object Cache enabled, a server cron job running a PHP version without the Redis/Memcached extension made WordPress cron process only one scheduled task per run, so background jobs (image optimization, critical CSS, backups) piled up. CacheLoop now tells WordPress when its cache backend is unreachable so cron falls back to the database, and updates refresh an outdated object-cache drop-in automatically.
• Fixed (Pro): if the PHP used by your server’s cron job can’t convert to WebP (a different PHP build than your website), “Optimize All” now pauses and tells you what to change instead of silently skipping images.
• Added (Pro): a status filter (all / errors / skipped / optimized) and an “Export CSV” button on the Optimized Images table, so you can review which images failed and why.
• Fixed (Pro): an image that was already converted could be re-flagged as an “unknown error” (and lose its savings figure) if it was processed a second time, for example by the upload job and “Optimize All” running together. Already-converted images are now recognised as done.
• Fixed: the Server Info panel showed “false” for disk space on hosts that restrict access to the server root; it now reports the space of your site’s own folder.
• Added: the Server Info panel now shows which web server you run (Apache, Nginx, LiteSpeed…) and whether it reads .htaccess.
• Improved: the Browser Caching PageSpeed tip no longer points Apache and LiteSpeed sites at Nginx; it now lists the causes that actually apply to them.
• Improved (Pro): “Optimize All” no longer converts a fixed 3 images per minute. Each background run now works for as long as your server’s PHP time and memory limits safely allow (always at least one image), so fast servers finish a large media library far sooner while slow shared hosts stay within their limits.
• Added (Pro): the “Optimize All” progress now shows a live estimated time remaining, and warns you when progress has stalled because WordPress cron isn’t running (with what to ask your host).

1.0.19

• Fixed: the “Clear All Cache” and “Purge This Page” admin toolbar buttons only appeared in wp-admin — the controller that registers them was only loaded on is_admin() requests, so the admin bar on the front end never got them (and the “Purge This Page” link’s own handler wasn’t reachable there either). The controller now loads on every request; “Purge This Page” shows automatically on any single post/page, front end included.
• Fixed: the “Purge This Page” admin bar button redirected to the homepage instead of back to the page you purged — its link was built against the site’s homepage URL instead of the current page’s permalink.
• Added: an “Exclude this page from the cache” checkbox on the Post/Page edit screen, so an individual page can be kept out of the cache without touching the global Whitelist/Blacklist settings.
• Changed: updated the bundled Freemius SDK from 2.13.2 to 2.13.4.

1.0.18

• Added: a “Download Nginx Config” button in Browser Caching settings, shown automatically when CacheLoop detects your server isn’t Apache/LiteSpeed. Generates a ready-to-use Gzip + static-asset browser-cache snippet, safe to drop straight into your existing Nginx server block, so Nginx-hosted sites no longer have to write these rules by hand.

1.0.17

• Fixed: the advanced-cache.php drop-in was only reinstalled when missing entirely, so sites that updated in-place (WordPress.org auto-update, or any path that doesn’t deactivate/reactivate the plugin) kept running a stale drop-in indefinitely instead of picking up drop-in changes from the new version — with no visible error. The self-heal check now compares file content, not just presence, and reinstalls on any mismatch.

1.0.16

• Fixed: the Premium build’s is_premium Freemius flag was hardcoded to false (same value as the free WordPress.org build), which hid the “Activate License” button on the Account page — clicking the only remaining button (“Sync License”) just reloaded the page with no effect. is_premium is now detected at runtime from the presence of Premium-only code, so Premium installs correctly show the license activation flow.

1.0.15

• Fixed: “Exclude First Images from Lazy Load” was hidden behind a Pro check even though the feature itself is implemented in the free code — the setting is now available to all users.
• Fixed: REST API Cache could serve a response generated for a logged-in/privileged request to a later, unauthenticated visitor without re-checking permissions; caching is now restricted to anonymous requests, wp/v2/settings and wp/v2/users were removed from the cacheable list, and the cache key now includes the query string so different request variations of the same route no longer share one cached file.
• Fixed: the Object Cache password field was sanitized with sanitize_text_field(), which can strip valid password characters; it’s now preserved as-is.
• Security: wp-content/cache/cacheloop/ (which can contain the Object Cache password in runtime-config.json) is now protected from direct HTTP access via .htaccess.
• Changed: internal AJAX/admin-post action names and nonce actions now use the full cacheloop_ prefix instead of the 2-character cl_ prefix, for consistency with WordPress.org’s minimum-prefix-length guidance.
• Fixed: deactivating could leave WP_CACHE enabled with the cache drop-in already removed if wp-config.php wasn’t writable, causing “headers already sent” warnings on every page until reactivated; the drop-in is now only removed once disabling WP_CACHE is confirmed.

1.0.14

• Fixed: CDN Integration’s inline CSS url() rewriting could fatal-error on any cached page (affected both the runtime rewriter and the pre-bootstrap drop-in).
• Fixed: the drop-in’s runtime configuration file was being wiped by the cache flush that runs right after every settings save, silently reverting CDN rewriting, custom Cache TTL, Device-Specific Cache, and Cookie-Based Cache Bypass to their defaults.
• Fixed: the admin toolbar’s “Clear All Cache” button pointed at an unregistered action and always produced a blank error page.
• Fixed: Varnish, Cloudflare, and Remove Unused CSS Safelist settings were silently discarded on every save.
• Changed: CDN Domain is now validated as a plain hostname (scheme, path, query strings, and javascript:/data: values are rejected).
• Changed: settings page scripts/styles are now properly enqueued instead of inline; internal class prefix and text domain updated for WordPress.org compliance.

1.0.13

• Fixed: a site could fatal error on every page load (front-end included) on hosts where the filesystem method resolves to non-direct (e.g. FTP) without stored credentials — the plugin’s own filesystem bootstrap wasn’t checking whether WP_Filesystem() actually connected before using it.
• Fixed: version-change cache invalidation and Image Optimization table self-heal were incorrectly skipped whenever the filesystem bootstrap above failed, instead of always running as intended.
• Changed: drop-in self-healing and wp-config.php editing now only run in wp-admin, not on every front-end request.

1.0.12

• Changed: the plugin version now shows at the top of the settings page sidebar, above “Dashboard”.

1.0.11

• Changed: settings cards with extra fields (CDN, Varnish, Cloudflare, Cache Whitelist, Remove Unused CSS) now stay collapsed until their toggle is switched on.

1.0.10

• Fixed: settings cards with extra fields below the main row (CDN, Varnish, Cloudflare, Cache Whitelist/Blacklist, Cookie Bypass, Remove Unused CSS) squeezed that content onto the same row instead of stacking it below.

1.0.9

• Added: Unused CSS Removal (Pro) — strips CSS rules unused on each page from the Minify & Combine output. Conservative by design (keeps anything it can’t verify safely); requires Minify & Combine CSS enabled.

1.0.8

• Added: Cloudflare Cache Purge (Pro) — mirrors CacheLoop’s own purges to Cloudflare’s edge via a scoped API Token, with connection test.

1.0.7

• Added: Varnish Cache Purge (Pro) — mirrors CacheLoop’s own purges to an upstream Varnish server, with connection test and VCL setup snippet.

1.0.6

• Added: Original/Optimized size columns in the Optimized Images table (Pro).
• Added: click-to-preview lightbox for optimized image thumbnails (Pro).
• Added: copy button for Debug Log and Server Info panels.
• Added: estimated time and disk space needed shown before “Optimize All” starts (Pro).
• Added: one-click optimize/revert directly from the Media Library, including bulk action (Pro).
• Added: site-wide progress notice while “Optimize All” runs in the background (Pro).
• Added: hosting panel, active plugins/theme, and load average in Server Info report.
• Fixed: Image Optimization AJAX requests could fail with a raw “unknown action” error when the “Optimize on Upload” toggle was off (Pro).
• Fixed: uninstalling the plugin left generated WebP files behind instead of cleaning them up (Pro).
• Fixed: admin-page AJAX calls firing in a simultaneous burst on load, which some hosts rejected.

1.0.4

• Added: Device-specific cache (mobile/desktop split).
• Added: CDN integration with URL rewriting (drop-in + PHP fallback + inline CSS).
• Added: Cache whitelist/blacklist with wildcard pattern support.
• Added: Cookie-based cache bypass.
• Added: Debug log panel in admin with refresh/clear.
• Added: Admin toolbar buttons (“Clear All Cache”, “Purge This Page”).
• Added: HTTP/2 Server Push for critical CSS.
• Added: REST API cache for common endpoints.
• Added: WP-CLI commands (wp cacheloop clear, status, preload, log).
• Added: Cache metrics dashboard (file count, disk usage, last purge).
• Added: Nginx configuration generator.
• Added: Concurrent write protection via file locking.
• Added: Cache versioning with automatic flush on update.
• Fixed: Double cache serving race condition.
• Fixed: CSS minification breaking strings and url().
• Fixed: Fatal error when premium files missing.
• Fixed: extract() error on runtime config.

1.0.3

• Configurable Cache TTL (1 hour to 7 days).
