you’re probably referring to “render-blocking CSS/JS” and “unused CSS/JS” 🙂
for render-blocking CSS: look into “inline & defer CSS”, more info in the AO FAQ
for render-blocking JS: make sure “force in head” is off
for unused CSS/JS: it is being reported as being Autoptimize’s, but AO merely aggregates all the CSS/ JS provided by your theme & plugins, so if you (really) want to tackle “remove unused CSS/JS” then you should look into your theme & plugins (you might be able to get some improvement using e.g. “plugin organizer” to only allow plugins to work on specific pages). Moreover the unused CSS/ JS will likely be different for different pages (or parts of your site), so that would lead to different autoptimized CSS/JS-files being loaded on different pages.
hope this clarifies,

The same happends with my page, render-defer errors for:
…css/autoptimize_582ce12….css(www.apus-peru.com)
…css/autoptimize_single_6647e8e….css?158…&ver=5.4.2(www.apus-peru.com)
…css/autoptimize_single_7d8ec40….css?158…&ver=5.4.2(www.apus-peru.com)

Can you start your own topic as per the forum guidelines @elain81 ? And before doing so; have a look at the “inline & defer CSS”-option, more info in the AO FAQ 🙂
