I just encountered an Error on page editing, error message as following “The supplied nonce is invalid.” any idea what does it mean? and how to fix it?

Hi, thanks for posting.
A nonce is a “number used once” to help protect URLs and forms from certain types of misuse, malicious or otherwise. WordPress nonces aren’t numbers, but are a hash made up of numbers and letters. Nor are they used only once, but have a limited “lifetime” after which they expire. During that time period the same nonce will be generated for a given user in a given context. The nonce for that action will remain the same for that user until that nonce life cycle has completed.
Does the issue persist if you log out and log back in again?
I’ve tried to clear the caches in Cloudflare CDN, and the problem has disappeared.
Super, glad to hear you’ve been making progress. If the issue reoccurs, please, let us know.
Cheers for now.
