I have installed Humminbird and Smush Pro plugins and ran the entire library optimization (about 14000 images). This worked well.
Now - i run Hummingbird test again and it tells me to smush the images, that are already smushed. This, Hummingbird, says, impacts the speed score drastically.
I have also the "force regenerate thumbnails" plugin installed. Dont know, if it needed with the latest WP theme, actually.
Your advice would be welcome and appreciated :slight_smile:
