Frequently Asked Questions (FAQ)
Do I need a LiteSpeed server to use this plugin?
No. While LiteSpeed-exclusive features (like server-level caching and ESI) require a LiteSpeed Web Server or QUIC.cloud, many core features like CSS/JS minification, image optimization, lazy loading, and CDN integration work on any server, including Apache and NGINX.
What is QUIC.cloud and how does it relate to LiteSpeed Cache?
QUIC.cloud is a content delivery network (CDN) created by LiteSpeed Technologies. It allows users on any hosting server (not just LiteSpeed) to take advantage of server-level caching, image optimization, and other advanced features by acting as a bridge. You can connect your site to QUIC.cloud through the LiteSpeed Cache plugin.
Is LiteSpeed Cache compatible with WooCommerce?
Yes. LiteSpeed Cache is fully compatible with WooCommerce. It includes smart purging, cache exclusion rules, and ESI integration to ensure dynamic content like shopping carts and account info remains accurate and uncached when necessary.
Will LiteSpeed Cache conflict with other caching plugins?
Potentially, yes. It’s recommended to disable or remove other caching plugins (like WP Super Cache, W3 Total Cache, etc.) when using LiteSpeed Cache to avoid performance conflicts or double caching issues. LSCache is a full replacement, offering both client- and server-side caching in one package.
Does LiteSpeed Cache optimize images?
Yes. It includes built-in image optimization tools that can compress images (lossless or lossy), convert them to WebP or AVIF, and lazy-load them for performance. Optimization is done via QUIC.cloud and includes bulk processing.
Will it improve my Core Web Vitals or PageSpeed scores?
In most cases, yes. Users frequently report improved Core Web Vitals and higher scores on tools like Google PageSpeed Insights and GTmetrix after enabling LiteSpeed Cache features like critical CSS, JS deferment, and image optimization.
Is it really free?
Yes. The plugin is completely free and open-source, with no paid version. However, QUIC.cloud offers both free and premium CDN bandwidth and image processing tiers, depending on your site’s needs.
How often is LiteSpeed Cache updated?
Very frequently. The plugin is under active development. As of August 2025, the latest version is 7.3.0.1, released on July 30, 2025, with continuous improvements, new features, and bug fixes.
