Wordpress LScache Plugin: Litespeed UCSS breaks mobile menu on Astra PRO
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello although I am also seeing this with the people of Astra, maybe you can help us here too im using Litespeed cache to optimize my website, the UCSS function (UNIQUE CSS) makes the site has a single css file and not several as it has at the moment (which pagespeed insights detect and punishes on score with reduce unused css ). After enabling Unique CSS, the page score increased by 8/10 points making the web far exceed 92 points in pagespeed insights mobile which is what google recommends, and Reduce Unused CSS was no longer a suggestion Instead, it was listed under the things the site does right. The problem is that the mobile menu is completely broken, the hamburger appears but clicking on it does nothing, it just doesnt work If someone knows how to solve this, I would greatly appreciate it, since it is the only thing left for me to optimize on my sites. support number JFJOALTA Regards, Lucas The page I need help with: https://dolcepanna.com.ar Have you already read this? https://blog.litespeedtech.com/2021/12/13/fix-incomplete-ucss/ https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/ if in fact I had read it, the problem is that when trying to add the missing .css to the Whitelist, other Astra Css classes were broken, and for example it stopped taking some fonts or image styles. i dont know why Im also going to try again adding the .css of the menu and update here
