Step 1 - Log in to WordPress and add a new plugin

Step 2 - Find the plugin and click Install Now

Click Activate to enable Litespeed

Step 3 - Next, you need to log in to cPanel and edit your .htaccess file (click here for a guide) to remove the default config.

One: Delete this text

## LITESPEED WP CACHE PLUGIN - Do not edit the contents of this block! ##

RewriteEngine on
CacheLookup on
RewriteRule .* - [E=Cache-Control:no-autoflush]
RewriteRule min/\w+\.(css|js) - [E=cache-control:no-vary]
### marker CACHE RESOURCE start ###
RewriteRule wp-content/.*/[^/]*(responsive|css|js|dynamic|loader|fonts)\.php - [E=cache-control:max-age=3600]
### marker CACHE RESOURCE end ###
### marker FAVICON start ###
RewriteRule favicon\.ico$ - [E=cache-control:max-age=86400]
### marker FAVICON end ###

## LITESPEED WP CACHE PLUGIN - Do not edit the contents of this block! ##
# END LSCACHE
# BEGIN NON_LSCACHE
## LITESPEED WP CACHE PLUGIN - Do not edit the contents of this block! ##
## LITESPEED WP CACHE PLUGIN - Do not edit the contents of this block! ##
# END NON_LSCACHE

Two: Add this text to the top

# BEGIN LSCACHE

CacheEnable public /
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^(HEAD|GET)$
RewriteCond %{REQUEST_URI} !^/(wp-admin|wp-login.php|wp-cron.php)
RewriteRule .* - [E=Cache-Control:max-age=120]

# END NON_LSCACHE

The page should look like this.

# BEGIN LSCACHE

CacheEnable public /
RewriteEngine on
RewriteCond %{REQUEST_METHOD} ^(HEAD|GET)$
RewriteCond %{REQUEST_URI} !^/(wp-admin|wp-login.php|wp-cron.php)
RewriteRule .* - [E=Cache-Control:max-age=120]

# END NON_LSCACHE
# BEGIN WordPress

RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress
