How to optimize the site speed using hummingbird?
I am using hummingbird (pro) plugin to optimize the site speed from my website, the software suggested me to compress the css and js file, I did what they suggested, but the website (lay-out, and some featured is gone), so I turn of the advance option. Is there any body can advice me which css and js file that should not be compressed or the combination of file that can not be touch?
I am using elementor, and generatepress theme.
Thank you for advice
