Wordpress LScache Plugin: Litespeed FOUC error
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hey there, Ive been having FOUC problems on my website while using all the three options i.e. load CSS async, critical CSS, and critical CSS in background ON. Please help me out with the issue as load async drastically improves my site performance. Also, Ive tried various other CSS combinations but none of them worked. I am an hostinger sever and LS cache user The page I need help with: https://uprisehigh.com Hi, Please check this page Best regards, Hey there, I tried what you said? Still, the FOUC error is there on my website. You can check the website as well where I have already enabled everything and you can check what is wrong over there. Also, Ive kept the settings on just for you to check what is causing the FOUC problem. Please helpI dont see the FOUC now you can always check the CCSS rule on your page , see if it is inserted or not Sorry but the FOUC still exists. Here is the link for the FOUC image that I am still getting? I can see that the CCSS is inserted on every page but the problem still exists which page is that ? I tested on my Android and my iPhone but didnt see any FOUC All the pages. You can check this page, or this, or this. go to page optm -> css -> Separate CCSS Cache Post Types -> put page save, purge CCSS and purge all , then let CCSS regenerate , see how it goes Still not resolved? Tried what you said Hi, well, sadly , I dont have solution. despite we always work on improve the CCSS engine , but it seems at this moment that our CCSS engine is not working well on your pages Best regards, Hey varunpahwa, You may have already done this but just throwing it out there. Make sure your browsers are up to date. Also, if your theme has a style cache, clear it. Try running it with CSS combine external and inline disabled. This has caused issues when my theme updated and when Chrome was out of date. As well, and always, check it with all your other plugins off and on a different theme. There are a ton of settings. And I do have my own issues. Im here searching for a solution to one. Anyway, just some things Ive learned. Maybe it will help.
