Wordpress LScache Plugin: Render blocking js in PageSpeed
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi. Thank you for a great plugin. I just activated the lazyload function, and it works great. However, on the one page where i have my image in above the fold content , i get an error message in Pagespeed saying min/lazyload.js is render blocking. On other pages, with images below the fold, it doesnt get any render blocking error. I have tried adding the image to the exclude list, and added data-no-lazy= 1 in image html. It still loads min/lazyload.js on that one page, and gives a render blocking from PageSpeed. Any way to solve this? Have lazyload.js inlined? Thanks This topic was modified 5 years ago by omma46. The page I need help with: https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fwww.rentekalkulator.com%2Foversikt-kalkulatorer%2F&tab=mobile Hi Omma46, May I ask which Path or entry you added as exclude? What I saw from source page still showing data-lazyloaded=1 instead of data-no-lazy= 1 . Would you mind to check settings again? and purge cache all , see if it works. Best, Eric Thank you for your reply When i look at the page-source, it shows data-no-lazy= 1 . But the remark is still there in PS. It shows no error from pages where images is below the fold and lazyloaded. This is the only page where i have the images above the fold. It is a small size image, so i dont need it lazyloaded, but i would like to get 100/100 on PS, and cant seem to get it with lazyload.js beeing render blocking. Hi Omma46, Can you try set Optimization Settings> Exclude JQuery as Disabled, if there is no error from Chrome developer tool, then run it again on PageSpeed site and see if it getting better? Best, Eric I tried this solution, but it still show up with lazyload.js being render blocking. I have added the image to excluded list, and also added data-no-lazy= 1 to page html, inside image tag. Any way to defer min/lazyload.js? That would keep it from render blocking. Hi Omma46, After I enabled JS defer, I can see defer data-deferred=1 from page source. You can try add this attribute and see if it works or not. Best, Eric Perfect, this solved the problem. Thank you for great support.
