Hi
Pagespeed insights shows the following file in Asset Cleanup does not use passive listeners to improve scrolling performance:-–
/wp-content/cache/asset-cleanup/js/head-xxxxxxxxxxx.js
What can I do to correct this??
Thanks.
@moreechika the file you’re referring to is a combined JS one (made of the remaining loaded JS files). Now, you would get the same warning if you were to load the files individually (e.g. without the combine JS option enabled). The JS code remains the same after Asset CleanUp combines the file. Try to make a test without the combine option enabled.
It’s the same thing as with render-blocking CSS/JS. If it’s render-blocking, it will stay like this whether you load five files or one file made of those five. There’s a post explaining it here: https://www.assetcleanup.com/docs/can-the-plugin-load-render-blocking-css/
