Wordpress LScache Plugin: Hamburger menu broken after CSS optimisation
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hej! I have a strange behaviour with LiteSpeed CSS Optimization (most probably). I have WordPress with Twenty twenty two theme and Litespeed cache enabled in hosting environment, so corresponding plugin has been added to my WordPress installation. Everything is updated up to latest version available. During the setup I tried different options on/off and checked it against pagespeed rank and noticed that enabling Load CSS Asynchronously increased pagespeed rank a lot. But it broke the hamburger menu we use for mobile. You say ? just turn it off, but theres a problem: I did so and this brought everything alright back. Until I tried to push Run CCSS Queue Manually when I tried to find a way to push menu back to work. After that ??hamburger menu doesnt work whenever options I put on or off. Temporary I disabled hamburger menu on the site, because it is hard to use it without a navigation. But it doesnt look great, so it would be nice to bring hamburger menu back. Thanks in advance! maybe its something else than load css async if you turn off all in CSS tab , purge all , how does it go ? maybe its something else than load css async Maybe ? Im not sure, but isnt hamburger menu rather JS than CSS? if you turn off all in CSS tab , purge all , how does it go ? Done. Unfortunately, still not working. what if you completely reset to default setting ? you can do so in toolbox -> import/export Dear @CacheCrawler After resetting all settings in toolbox -> import/export everything works. Either on desktop or on mobile. okay , that means one of the option caused issue , now please try narrow down which one was it , and then we will see what to do next. Well, i cant reproduce it step by step, but most probably it is because of combination of Load CSS Asynchronously and UCSS. but if you only use CCSS or only UCSS, it doesnt happen ?
