Wordpress LScache Plugin: Generate Critical CSS Issue
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, my site is hosted on a Litespeed server. I downloaded your plugin and went through the page optimization tab. I read your documentation about the critical CSS, I dont know whether it is working or not. Also, I found this under Load CSS Asynchronously ?> WARNING You will need to set Domain Key to use the online services. Click here to set. Since I am on a Litespeed server, I dont need the QUIC.cloud services. So, even though I dont set the domain key or activate the QUIC.cloud services, will the LOAD CSS ASYNCHRONOUSLY option & CRITICAL CSS work? And I am using LiteSpeed Cache Plugin only on my Sub-folder domain. This topic was modified 2 years, 3 months ago by qph9697. The page I need help with: https://questionpapershub.com/free-job-alert/ Hi, Since I am on a Litespeed server, I dont need the QUIC.cloud services. Regardless what webserver you are using , if you want to use online services like image optimization , CCSS generation ?etc , you will need to set a domain key and CCSS will not work until you have requested a domain key. Best regards, Okay, I have requested for the domain key. I only require CCSS generation, and no image optimization. So just to get the CCSS functionality, is it compulsory to associate my site with QUIC.cloud? Because, I did earlier associated my site with QUIC.cloud, and it proved to have a negative impact on my site and which is why I removed my site from QUIC.cloud. Hi, For any online services , you will need to request the domain key , I did earlier associated my site with QUIC.cloud, and it proved to have a negative impact on my site and which is why I removed my site from QUIC.cloud. it is not necessary to link to QC, you can keep it as anonymous. QC consists by several different services , CDN , CCSS, Image opt , LQIP ?etc , all these services will need domain key you will need to request domain key , but you can choose use or not to use other features like CDN but I am more curious about how that negatively impacted your site ? maybe we can sort that out as well. Best regards, Hey Hi, the critical CSS os not loading. Many users have complained about seeing they are able to see our page without any CSS for sometime, wherever they load our page. And I did tried testing this too, I can also see a HTML view of my page, and then after some times, it goes back to normal. I have enabled all three, Load CSS Asynchronously , Generate Critical CSS , Generate Critical CSS In Background , but still its not working. Here is a screenshot, https://ibb.co/hyhPfcJ Please help me with this. but I am more curious about how that negatively impacted your site ? maybe we can sort that out as well. I have litespeed cache plugin installed on my sub-folder domain, and my my domain uses w3tc cache plugin. When I activated QC, my main domains loading time got affected and both FCP and FID increased. Which is why I had to remove the QC. Hi, for CCSS, please check this wiki I have litespeed cache plugin installed on my sub-folder domain, and my my domain uses w3tc cache plugin. When I activated QC did you change the DNS record per QC requested to the CNAME record? and both main site and sub-dir site will need use LSCWP and link to QC account , otherwise CDN wont work properly.
