Wordpress LScache Plugin: Reduce unused CSS and JS LiteSpeed Cache
Last Updated on: Wed, 15 Apr 2026 00:00:02 When I ran a performance test for my domain on https://developers.google.com/speed/pagespeed/insights/” it suggests reducing CSS and js. but when I took the path of CSS and JS, its coming from the LiteSpeed cache folder. PATH:- /wp-content/litespeed/css/59f0a758783742a3878d3e51918ecf45.css?ver=52f8e /wp-content/litespeed/js/8a97736af9ea95ea700e7d733b805335.js?ver=05335 How can I minimize and remove the warning from google page speed and gtmatrix? screenshot- https://paste.pics/DH3X1 This topic was modified 1 year, 3 months ago by netesh. The page I need help with: https://apnapasand.com/ Hi, We release our new feature UCSS in version 4.0. You can upgrade to version 4.0+ in Litespeed Cache sidebar menu > toolbox > beta test. Then navigate to Page Optimization > CSS Setting > turn on Generate UCSS . Regards, Lehan I have upgraded Litespeed and enable Generate UCSS but unfortunately, I still see unused CSS and Js same size in the google insight speed test.https://apnapasand.com/ Screenshot:- https://paste.pics/DHDEB Just now I noticed, After enabling Generate UCSS, the website in the mobile view menu is broken. all menus coming at the bottom of the page. I am using oceanwp themes. Hi, Then can you disable Generate UCSS and try to enable Guest Mode and Guest Mode Optimization under General. After that, make sure to purge the site through purge all ? ccss. See if the problem still exist. Regards, Lehan Sure, I will try your solution and monitor it. I have one more question, After upgrading to 4.1 why I am getting below warning. WARNING LSCache caching functions on this page are currently unavailable! attached the screenshot:- https://paste.pics/DHX3T Hi, Please navigate to Litespeed Cache > CDN > enable QUIC.cloud CDN , see if the warning goes away. Regards, Lehan Thanks a lot Lehan, its working.
