LiteSpeed is a high-performance web server that works seamlessly with WordPress. When properly configured in cPanel and WordPress, it significantly improves website speed, security, and performance.

This guide explains how to configure LiteSpeed on both cPanel and WordPress using the LiteSpeed Cache (LSCache) plugin.

Requirements

Before starting, ensure:

• Hosting uses LiteSpeed Web Server

• WordPress is installed

2. Look for LiteSpeed Web Cache Manager
   (If present → LiteSpeed is active)

If missing, contact your hosting provider.

Step 2: Enable SSL (Important)

LiteSpeed Cache works best with HTTPS.
