Exclude caching files at Lighthouse?

    Hi all,

    I use W3 Total Cache for our multisite wordpress to increase performance, especially with Lighthouse.

    However, in the results on Lighthouse I always see the caching (minify) files that need to be eliminated.

    E.g:
    – Remove unused CSS: Error source: /wp-content/cache/minify….
    – Does not use passive listeners to improve scrolling performance: error source is again a cache file ….js

    What is the cause. How can I exclude the cache files at Lighthouse?
    Is there a “best w3tc” Setup?

    Thanks in advance
    M.

    Hello @eisik

    Thank you for your inquiry and I am happy to assist you with this.
    W3 Total Cache only minifies the files. So the unused CSS and Do not use passive listeners to improve scrolling performance is the issue with the files before they were minified. And since they were minified the issue is now within the Minified files.
    Bot issues are unrelated to W3 Total Cache as W3TC cannot solve this for you.
    Both issues, Do not use passive listeners to improve scrolling performance and Remove unused CSS need to be addressed before minifying as W3 Total Cache, again, cannot disable passive listeners and remove unused CSS. SO this needs to be done in development first.
    Thanks!

    Hello @vmarko,

    Thank you for quick reply.

    How can I solve this problem? Is there a way to undo the minified files? e.g. if I disable minify for js and css, are the files visible again? Then I could solve the problem myself.

    Second question; is there a tutorial on how best to set w3tc?

    Thanks a lot.

    Hello @eisik

    Yes, simply disable Minify in Performance>General settings, save all settings and purge the cache. After that, the files will be unminified.
    The optimal W3 Total Cache configuration takes into account a number of factors: your theme, your plugins, the technologies available on the server. Since everyone’s site and traffic and theme are different, there is no one size fits all solution.
    Please check out the documentation for more details about the features.
    Thanks!
