How to Configure LS Cache in WordPress

Posted on by Prakash Tiwari

Website speed is essential. A slow site can drive visitors away and hurt your Google rankings. If your website takes too long to load, people may leave before seeing your content.

One of the best ways to speed up a WordPress site is to use LS Cache (LiteSpeed Cache). LS Cache stores website data to reduce load times. It works better than most caching plugins because it integrates directly with LiteSpeed web servers.

This guide will show you how to configure LS Cache in WordPress. Whether you’re new to caching or have used it before, this guide will help you optimize your website for maximum speed.

Step 1: Install and Activate LS Cache

Before configuring LS Cache, install it on your WordPress website.

How to Install LS Cache Plugin

  1. Log in to WordPress
  2. Go to Plugins > Add New
  3. Search for LiteSpeed Cache
  4. Click Install Now
  5. Click Activate

Once activated, a LiteSpeed Cache menu will appear in your WordPress dashboard. Now, it’s time to configure the settings.

Step 2: Enable Basic Cache Settings

LS Cache has many options, but you only need a few settings to see instant improvements.

How to Enable Caching

  1. Go to LiteSpeed Cache > Cache
  2. Turn ON Cache – This enables page caching.
  3. Set Cache TTL (Time to Live) – The default setting is OK (600 seconds).

This setting ensures that WordPress pages load faster by serving cached versions to visitors.

Step 3: Optimize Page Load Speed

Caching is only one part of speeding up your website. LS Cache also helps with other optimizations.

Enable HTML, CSS, and JavaScript Minification

Minification removes unnecessary spaces and code from your site files, loading them faster.

  1. Go to LiteSpeed Cache > Page Optimization
  2. Click on the CSS Settings tab
    • Turn ON CSS Minify
    • Turn ON CSS Combine
  3. Click on the JS Settings tab
    • Turn ON JS Minify
    • Turn ON JS Combine
  4. Click Save Changes

Now, your website will load CSS and JavaScript files more efficiently.

Step 4: Optimize Images for Faster Loading

Images often slow down websites. LS Cache automatically optimizes images to reduce file sizes without losing quality.

How to Enable Image Optimization

  1. Go to LiteSpeed Cache > Image Optimization
  2. Click Send Optimization Request
  3. Wait for images to be processed (this may take a few minutes).

This process reduces image sizes, making pages load faster.

Step 5: Use Browser Caching

Browser caching helps store website files locally on a visitor’s device. This means returning visitors don’t have to load everything again.

How to Enable Browser Caching

  1. Go to LiteSpeed Cache > Cache
  2. Click on the Advanced Settings tab
  3. Turn ON the Browser Cache
  4. Click Save Changes

Now, repeat visitors will experience faster loading times.

Step 6: Clean Up the Database

A cluttered database can slow down your website. LS Cache automatically removes unnecessary data to keep things running smoothly.

How to Optimize Your Database

  1. Go to LiteSpeed Cache > Database
  2. Enable the following settings:
    • Post Revisions Cleanup (Removes old versions of posts)
    • Trash Cleanup (Deletes unnecessary items)
    • Optimize Tables (Improves database speed)
  3. Click Save Changes

Now, your database will stay clean and fast.

Step 7: Use QUIC.cloud for Advanced Optimization

QUIC.cloud is an optional CDN (Content Delivery Network) that works with LS Cache. It helps speed up websites worldwide by serving cached content from multiple locations.

How to Connect QUIC.cloud

  1. Go to LiteSpeed Cache > General Settings
  2. Click Request Domain Key
  3. Follow the on-screen instructions to set up QUIC.cloud
  4. Once activated, go to LiteSpeed Cache > CDN
  5. Turn ON QUIC.cloud CDN

This setting ensures your site loads faster for global visitors.

Step 8: Test Your Website Speed

Once you’ve configured LS Cache, test your website speed to see improvements.

How to Test Website Speed

  1. Go to GTmetrix (gtmetrix.com)
  2. Enter your website URL
  3. Click Analyze
  4. Review the speed score

You should see faster loading times after enabling LS Cache settings.

Common Issues and How to Fix Them

1. Website Layout Looks Broken After Enabling Minification

  • Disable CSS or JavaScript Combine under Page Optimization.

2. Some Images Are Not Loading

  • Clear the cache by going to LiteSpeed Cache > Toolbox > Purge All.

3. My Site Is Still Slow After Enabling LS Cache

  • Check if your hosting supports LiteSpeed Server. Some hosting providers use Apache, which limits LS Cache’s performance.

Conclusion

Configuring LS Cache in WordPress dramatically improves website speed. With the correct settings, your site will load faster, rank higher, and provide a better user experience.
