Ideal for development, testing, or any time you need browsers to always load the freshest files. ### Key Features * **Cache Busting** — Appends a dynamic version parameter to CSS/JS URLs so browsers skip the cache * **Two Busting Methods** — Force Refresh (timestamp, every page load) or Smart Refresh (file modification time, only when the file actually changes) * **File-Type Control** — Apply cache busting to both CSS & JS, CSS only, or JS only * **Strip Existing Version** — Remove WordPress’s built-in `?ver=` before adding ours, preventing duplicate parameters * **Per-Page Override** — Disable cache busting on individual pages or posts via a meta box in the editor (new in 1.2.0) * **CDN Support** — Optionally apply cache busting to external/CDN-hosted files * **Exclude Paths** — Skip specific files or URL fragments * **Browser Caching (.htaccess)** — Add long-lived `Cache-Control` headers for images, CSS, JS, and PDF files * **Configurable Cache Duration** — 60 seconds up to 1 year * **Admin Bar Quick Toggle** — One-click enable/disable from the toolbar * **Statistics Dashboard** — See how many CSS and JS files have been processed * **Clear Cache Button** — Flush WordPress object cache and compatible caching plugins in one click * **Admin Notice** — Optional reminder when cache busting is active (handy for production sites) * **Clean Uninstall** — Removes all settings and .htaccess rules when the plugin is deleted ### How It Works When cache busting is enabled, the plugin adds a `?ver=` query string to every CSS and JS URL loaded on the frontend. Browsers treat each new URL as a fresh request, ignoring any cached copy. Choose **Force Refresh** for development (version changes every page load) or **Smart Refresh** for production (version changes only when the file timestamp changes). The optional `.htaccess` browser-caching feature writes `Cache-Control` headers so returning visitors load static assets straight from their browser cache. ### Use Cases * **Development** — See theme/plugin changes instantly without clearing your browser cache * **Staging** — Verify the latest files are loaded during QA * **Production** — Enable browser caching for performance while still being able to bust the cache on demand * **Troubleshooting** — Quickly rule out stale-cache issues ### Technical Details ### Developer Hooks **Action** do_action( ‘disable_css_js_cache_cleared’ ) — fires when the Clear Cache button is clicked. **Filters (WordPress core, used by this plugin)** style_loader_src, `script_loader_src` ### Constants ``` DISABLE_CSS_JS_CACHE_VERSION — current plugin version string DISABLE_CSS_JS_CACHE_FILE — absolute path to the main plugin file DISABLE_CSS_JS_CACHE_DIR — absolute path to the plugin directory (with trailing slash)

Requirements

``` * WordPress 5.5 or higher * PHP 7.4 or higher * Apache with `mod_headers` (browser- caching feature only) * Writable `.htaccess` (browser-caching feature only) ## Screenshots [⌊Plugin settings page⌉⌊Plugin settings page⌉[ Plugin settings page ## Installation **Automatic** 1.

No. The plugin hooks into WordPress’s existing script/style loader with minimal overhead. When Smart Refresh is used, the overhead is limited to a single `filemtime()` call per file, only on the frontend. ### Does this work with page caching plugins? Yes. This plugin modifies file URLs, not page output, so it works alongside WP Super Cache, W3 Total Cache, WP Rocket, LiteSpeed Cache, and similar plugins. ### What is “Strip Existing Version”? WordPress adds its own `?ver=X.X` to enqueued files. With Force Refresh enabled, that becomes `?ver=6.7&ver=1234567890`. Enabling Strip Existing Version removes WordPress’s parameter first, leaving only ours. ### What is the Per-Page Override? When enabled, a “Cache Busting” meta box appears on every public post/page in the block editor and classic editor. Checking the box disables cache busting for that specific page — useful for pages where you want the browser to cache assets normally. ### Will this affect admin-area scripts? No. Cache busting only runs on the frontend. ### What happens to my .htaccess when I deactivate the plugin? All browser-caching rules written by this plugin are automatically removed from `. htaccess` on deactivation. ### Does this work on Nginx? The `.htaccess` browser-caching feature requires Apache with `mod_headers`. The cache-busting feature (URL versioning) works on any server. ### Is this multisite compatible? Yes. The uninstall routine cleans up options for every site in the network. ### Does this work with CDN? The cache-busting feature works with CDN-hosted files when the CDN / External Files option is enabled. Note that some CDNs strip query parameters — test before enabling in production. ## Reviews ![](https://secure.gravatar.com/avatar/f2bd7cf2bf18e1d661e28206eb00ebd15c4db4360c86605ee1125bb6d9584220? s=60&d=retro&r=g) ### 󠀁[Superb Plugin!](https://wordpress.org/support/topic/superb-plugin-408/)󠁿 [zircotech](https://profiles.wordpress.org/zircotech/) 3 februarja, 2024 This plugin has become my go-to tool for making quick updates without the headache of caching delays.
