With a single setting, you can remove that parameter from public-facing asset URLs while keeping all other URL parameters intact. WordPress uses version query strings to help browsers recognize updated files. Some site configurations prefer URLs without the `ver` parameter, for example when using a specific legacy proxy or caching setup. This plugin offers that choice without changing physical files or requiring edits to a theme. #### What the plugin changes An enqueued asset URL may look like this: ``` https://example.com/wp-content/themes/example/style.css?ver=1.2.3 ``` When the plugin is enabled, the filtered URL becomes: ``` https://example.com/wp-content/themes/example/style.css ``` If an asset has other query parameters, such as `?theme=dark&ver=1.2.3`, the plugin removes `ver` and leaves `theme=dark` in place. It does not remove query parameters with other names. #### Key features * **Automatic URL cleanup:** Removes the `ver` query argument from enqueued script and stylesheet URLs on the public site. * **Script module coverage:** Applies the same URL cleanup when WordPress filters enqueued script module URLs. * **Resource hints and preloads:** Processes supported resource hint and preload URLs in addition to standard script and style URLs. * **Simple on/off setting:** Enable or disable cleanup at Settings > Asset Version Killer in the WordPress dashboard. * **Enabled on activation:** Cleanup is enabled by default when the plugin is first activated. * **Handle exclusions:** Developers can exclude specific script or style handles from URL cleanup through a WordPress filter. * **Custom URL filtering:** Developers can inspect or modify the final cleaned asset URL with a filter. * **No frontend assets of its own:** The plugin does not enqueue its own frontend JavaScript or CSS, and it does not create custom database tables. #### How it works Simpli Asset Version Killer uses WordPress’s built-in filters to modify URLs as WordPress prepares asset tags and resource references. It uses `remove_query_arg()` to remove only the `ver` argument. Regular WordPress dashboard pages are not altered. WordPress AJAX requests can still run URL filters, depending on their context. No theme modification or rewrite-rule configuration is required. The plugin’s Settings page provides a checkbox to turn this behavior on or off. #### Developer hooks For custom integrations, these hooks are available: * `simpli_asset_version_killer_excluded_handles`: Filter the list of handles excluded from cleanup. Receives the excluded-handles array, current handle, and URL. * `simpli_asset_version_killer_cleaned_src`: Filter an asset URL after `ver` has been removed. Receives the cleaned URL, original URL, and handle. * `simpli_asset_version_killer_prevent`: Override the enabled state for a request. Return `true` to force cleanup, `false` to prevent it, or `null` to use the saved setting. These hooks are intended for developers comfortable adding custom code. Ordinary users do not need them. #### Caching and compatibility considerations **Removing the version parameter is optional and does not guarantee faster loading or better performance test scores.** Modern browsers and many CDNs already cache URLs containing query strings correctly. WordPress adds the version parameter for cache busting, so removing it can cause a browser or CDN to keep an older CSS or JavaScript file after an update. Consider leaving the plugin disabled if your current caching setup works well. When enabled, test important pages after theme and plugin updates, and purge relevant caches if visitors receive outdated assets. Some third-party assets may depend on a version argument; developers can exclude their handles if necessary. ## Installation 1. Upload the `simpli-asset-version-killer` folder into the `/wp-content/plugins/` directory, or install the plugin through the WordPress Plugins screen. 2. Activate Simpli Asset Version Killer in Plugins. 3. Visit Settings > Asset Version Killer to confirm that version cleanup is enabled. 4. Optional: turn off the setting if you want WordPress to keep its normal asset version parameters. ## FAQ ### Which URL parameters are removed? Only the parameter named `ver` is removed. Other query parameters are preserved. ### Does this modify CSS and JavaScript files? No. Only filtered asset and resource URLs are changed. The plugin does not edit, minify, concatenate, or regenerate your source files. ### Is there a settings page? Yes. Go to Settings > Asset Version Killer to turn cleanup on or off. The plugin is enabled by default after activation. ### Does it change WordPress admin pages? Ordinary WordPress admin pages are excluded from URL cleanup. Requests handled through WordPress AJAX may be treated differently because the code allows processing during AJAX requests. ### Can I keep version strings on selected scripts or styles? Yes. Developers can add handles to the `simpli_asset_version_killer_excluded_handles` filter to skip particular assets. ### Will removing ver always improve performance? No. Modern caches usually handle query-string URLs. This plugin is intended for sites with a specific reason to remove the parameter, not as a guaranteed speed optimization. ### Why might older CSS or JavaScript appear after an update? The version string is part of WordPress’s cache-busting behavior. If you remove it, previously cached assets might remain in use. Purge your browser, page, or CDN cache as appropriate. ### What happens when I deactivate or uninstall the plugin? Deactivation stops the plugin from filtering URLs. Uninstallation removes the plugin’s saved enable/disable option. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Simpli Asset Version Killer” is open source software.
