Once the plugin is activated, go to: LiteSpeed cache >> Cache >> and click on Save Changes >> to enable caching:
LiteSpeed Cache has a ton of great features, which can be split into two main
departments: Page caching and Page optimisation.
Page caching works with the existing site code – it caches it and serves it faster on the next visit. In most cases you can use that out of the box, without any changes needed.
Some of the page caching options you’ll find in the plugin are:
Server-side page caching – That’s the plugin’s core functionality – using the server to generate cached pages rather than the slower and more resource intensive PHP.
QUIC.CLOUD – the first and only content delivery network with the ability to cache dynamic WordPress pages… for FREE!
Image optimization – Speed up the site by reduzing the size of the images! There’s also a quick convesion to the next gen WebP format.
