I have a strange problem suddenly that all my wordpress admin backend resources cannot be loaded if I switch on Cloudflare, making it impossible to enter backend. I did not make changes to anything. It just… happened.
Front-end is relatively fine: only missing a few images.
I have whitelisted all cloudflare IPs in CSF and also used wordfence cloudflare-IP. And have been fine for a few weeks using CF without changing anything.
Any help is appreciated
