hasn’t made any difference.
Autoptimize aggregates all enqueued JavaScript and CSS. After that, it creates minified CSS and JavaScripts files and serves cached copies to your website as async or deferred.
This allows you to fix the render-blocking scripts and styles issue. However, please keep in mind that it can also affect the performance or appearance of your website.
Disable all your plugins, clear your cache (all of them) and re-load your site to check if everything is working how it should be. If it is, then now you can activate your plugins back 1 by 1 and as soon as it breaks you’ll know that the last plugin was the one causing issues (make note of this plugin, deactivate then keep doing the same).
