No. The plugin automatically detects when Elementor is in edit or preview mode and disables all frontend optimizations. Your editing experience remains unaffected. ### Is this compatible with caching plugins? Yes. This plugin works alongside popular caching plugins like WP Rocket, LiteSpeed Cache, W3 Total Cache, and others. It handles frontend optimizations while your cache plugin handles page caching. ### Will the JavaScript delay feature break my site? The delay feature automatically excludes jQuery, Elementor scripts, and all wp-* core scripts. You can add additional exclusions if needed. A fallback timeout ensures scripts load even without user interaction. ### How does Local Google Fonts work? When enabled, the plugin scans your site for Google Fonts, downloads the CSS and font files to your server, and serves them locally. This eliminates external requests to Google and helps with GDPR compliance. ### Does this work with WooCommerce? Yes. The plugin includes specific WooCommerce optimizations that conditionally load cart fragments, styles, and block styles only on shop-related pages (shop, product, cart, checkout, account). This reduces bloat on your blog and other pages. ### What happens if something breaks? Settings are automatically backed up before every save. You can restore any of the last 5 backups with one click. There’s also a “Safe Mode” profile that disables all optimizations for troubleshooting. ### Does this plugin collect any data? No. The plugin does not collect, track, or transmit any data. All features run entirely on your server. The auto-detect feature only fetches your own homepage – never external services. ### How does the database cleanup work? You can run manual cleanup or schedule automatic cleanup (daily, weekly, or monthly). The plugin removes excess post revisions (keeping a configurable number), old auto- drafts, trashed posts/comments, spam comments, orphaned metadata, and expired transients. ### Can I use different settings on different pages? Yes. The per-page overrides meta box (available on posts and pages) lets you disable specific optimizations like speculation rules, script deferral, JS delay, or local fonts on individual pages. ### Is this plugin multisite compatible? Yes. Each site in a multisite network has its own settings. Network activation is supported. ## Reviews ![](https://secure.gravatar.com/avatar/b936efb9cfeb45ab0794dbb0d43fb18afe4fb39ed10a50357c7bd4c13c638ace? s=60&d=retro&r=g) ### 󠀁[So far very good, maybe even a great plugin](https://wordpress.org/support/topic/so-far-very-good-maybe-even-a-great-plugin/)󠁿 [miki24](https://profiles.wordpress.org/miki24/) 13 Eanáir, 2026 1 reply I did a quick and short test of this plugin and it’s been great so far.
