Hi Frank,
Thanks for your message. What happened was that the image carousel made with Elementor Pro didn’t show in any browsers (Firefox, Chrome, IE, Safary). I checked everything on both Windows and Mac laptops, a Samsung smart phone and an iPad. Visitors saw a blank white space where the carousel should have been. I didn’t try excluding elementor JS from optimization, I would if I knew how to do so. I will search FAQ and try to do something because I liked Autoptimize very much. My site is a webshop (WP and Woocommerce) and I’m a bit afraid of experimenting.
Best regards, Katalin
