Wordpress LScache Plugin: Last update breaks Revslider page
Last Updated on: Wed, 15 Apr 2026 00:00:02 I was singing hosanna to Litespeed ever since Ive managed to bring pagespeed of my heavily overloaded index to 96/100 (mobile/desktop). However, it appears that the last update does something unhealthy to the Revolution Slider, as my index pages pagespeed dropped to measly 86/88. The rest of the site still flies at 96/99 or 97/100, so the culprit is definitely the revslider. TTI went from 1.4s to 3.2s, and CLS from 0.001 to 0.34. Nothing else have changed, just Litespeed got an update. Another observation, again a direct result of Litespeed update: lots of complaints from Ahrefs about broken javascript on many pages. The page I need help with: https://trentontalbot.com/ Hi, please provide the report number , you can get it in toolbox -> report -> click send to LiteSpeed Best regards, Thatll be BUXYNAQY. this part is slider ? how it is broken ? like what is expected behavior ? and what is the unexpected ? No, this is a testimonial block (although it certainly acts as a slider),it works fine. Revslider is a part that runs big slideshow on a top, and its a major sloth. However, until recent update Litespeed managed to keep it at 96/100 pagespeed. wait a second, what is the issue ? slider or score ? Score. Most likely related to how Litespeed (or your cloud service) optimizes the slider in question. Have you made any changes to lazy load routine? please try go to General page , enable guest mode and guest mode optimization , then purge all , see if it helps That completely eliminated revslider from Googles previews, but brought the pagespeed to 99/99? which is weird, since your ajax load causes an absolutely tectonic CLS. ?Correction: 99/99 is through Googles Pagespeed Insights. Lighthouse gives it 56, and properly notices CLS. Update: it seems that Load JS Deferred was a culprit. Whatever you changed in it in the last version caused massive amounts of CLS with Revolution Slider. Once I turned it off, mobile CLS dropped to 0. ?Additionally, Im getting quite a few 404 requests for /wp-content/litespeed/js/embed-scroll.min.js.map Why? please check these 2 pages https://blog.litespeedtech.com/2021/06/01/guest-mode-for-wordpress-in-lscwp-v4-0/ and https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/#devtools-failed-to-load-sourcemap 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,
