I have a Wordpress site, with WP Rocket pluging (with the Cloudflare add-on, with API key and Zone ID configured).
When, on WP Rochet, I try to create the “critical CSS”, WP Rocket shows me an error which seems to be related to Cloudflare:
I then changed the Firewall rules on Cloudflare, as the following print screen shows. But the WP Rocket error keeps coming. How can I solve this ?
Thanks a lot for your advices,
