Today I changed that page rule to cache everything under that domain, and then plugins started to give problems. I was very hard to update anything and see those changes.
I also had WP Rocket cache logged in users, which I unchecked now. I have WP Rocket IP whitelisted in CF, BTW, and cron jobs to run each hour in Siteground (for quick tests).
If I purge the cache in cloudflare, problems go away but return right after with WP Rocket not able to create Critical Path CSS files, and sending me to a blank page “The link you followed has expired.”
Thanks in advance!
