Hi!
Yes, I know all this, or at least I am aware of it – of course, all plugins are “up to date”. Speed Optimization is as you propose. WP Rocket knows about Cloudlfare, Cloudflare knows about XStore. There are Page Rules and further cache policies on top of this, and yet something, somewhere, is going wrong. I’m not saying that something will magically happen on its own, maybe I’m just counting on real advice on how to further verify it to find the real cause.
Thanks..
