Pending update

Continues pending update on my free cloudflare server account. How can I fix this

This generally means that the name servers have not been updated to be the ones provided for the account.

Pending is explained in Zone status ยท Cloudflare DNS docs.

You can check if the name servers are updated with things like whois and dig or third party sites, so you can check propagation. I use DNSChecker out of habit, but there are several other sites out there that can also check name servers.
