 * Hi,
 * I am trying to defer parsing of a JS script based on Google’s recommendation 
   and the plugin is not doing anything. I have tried several settings, but the 
   last ones are:
 * Enable Async JavaScript? > Checked
    Also enable Async JavaScript for logged in
   users? > Checked Also enable Async JavaScript on cart/ checkout pages? > Checked
   Async JavaScript Method > Defer jQuery > Defer Scripts to Defer > [https://www.carlosazuaje.com/wp-content/cache/minify/ad843.js](https://www.carlosazuaje.com/wp-content/cache/minify/ad843.js)
 * I am still getting the same message on Google’s PageSpeed Insights and also on
   GTmetrix.

 * That’s because AsyncJS adds defer (or async) to JS that was added to wordpress
   using wp_enqueue_script Carlos, but you have another plugin that is minifying
   that enqueued JS and AsyncJS does not “see” that. So if you want to use asyncJS
   to async your JS, you will have to disable JS minification (or use anohter minifier).
 * hope this clarifies,
    frank

 * Hey Frank,
 * Thanks for the fast response. What do you recommend then to minify all my JS 
   but also defer the script? Obviously, I don’t want to only defer the script and
   not be able to minify the rest of my JS.

 * I might be am biased, but if I were you I would give Autoptimize a try 😉

 * I actually gave it a try a while ago but had to deactivate it because it gave
   me problems.
 * So in summary, AsyncJS won’t work if I have another plugin that is not Autoptimize
   minifying my JS, right?

 * depends on how the minifying plugin works actually, if it only replaces the script
   source but leaves the rest of the script tag (including the async or defer flag)
   intact, then you’re good to go. apperantly the one you’re using now (which one
   is that) works differently.
 * regarding AO; don’t know when you tried and what the issue was, but AO now also
   has an option not to aggregate (which means it acts more or less how your current
   minifier works). and well, almost all problems can be fixed by [some troubleshooting](https://wordpress.org/plugins/autoptimize/#configuring%20%26%20troubleshooting%20autoptimize)

 * Thank you.
 * I am using W3 Total Cache, which minifies HTML, CSS and JS (same as Autoptimize).
   I understand that running the two plugins together causes problems, that’s why
   I only have W3 Total Cache activated.
 * If I understand you correctly, are you saying that I can run Autoptimize together
   with W3 Total Cache and make AsyncJS work?

 * you can, if you disable all minification in W3TC to avoid conclicts.

 * Is that the only way to make AsyncJS work?

 * well, you could try finding another minification plugin, but I don’t know how
   the others work tbh, so can’t say for sure. it is possible fast velocity minify(
   which is great) can help and maybe that even has asyncing in it.
