Wordpress LScache Plugin: Can I get confirmation if UCSS works for mobile or not?
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi there, A new user of this plugin and so far very impressed with it. I am testing the UCSS feature in the page optimisation section, and what I found is that when I have this feature enabled, the mobile page (same content, just responsive) does not use the UCSS but instead its loading all css files separately as if there is no page optimisation. I googled and somewhere I found that last year there was a comment saying this UCSS feature does not work for mobile. I just want to confirm if this is still the case? And if it is the case, is it possible to have the desktop using UCSS whilst the mobile still using combined CSS, with the CCSS feature instead? If I do NOT use UCSS, and only use the CCSS and load other css async, does this work with mobile consistently? Is there any other feature of this tool which only works for desktop but not mobile? Thank you! Sorry after further testing it seems UCSS does work on mobile, however it seems when I load up the page the first time on a mobile device, it doesnt display the styles probably. It seems to me its using the desktop UCSS file on mobile, which pretty much means the style is all messed up. If I then refresh the page, it displays fine. On Quic.cloud, I can see that only 1 request of UCSS is stored, which does not seem to distinguish between desktop and mobile. Did I miss something here? Is the cloud supposed to store 2 different UCSS files for mobile and desktop? If thats the case, what about tablet? Thank you! If you are using services like UCSS, you should enable Cache Mobile Litespeed Cache > Cache > Turn Cache Mobile ON Thank you! I can confirm that I do have Cache Mobile on. Is there something else I have missed? Also I am not on openlitespeed server, but I did sign up for the QUIC.Cloud CDN. At the moment its verifying DNS. Is this the reason why its not working? Hi, Please go to sidebar menu > Litespeed Cache > Cache > enable Cache Mobile , this will create a cache copy for mobile visits. Regards, Lehan Hi, Please provide your report number, you can get it from admin sidebar menu > Litespeed Cache > Toolbox > Report > click Send to Litespeed . Regards, Lehan Hi, Im going to mark this topic Resolved , due to lack of activity. If you still need help, please feel free to re-open it. When re-open it, please also change the topic status to not solved Best regards,
