Question

caching

Greetings

More to the point, I have a WordPress site.
I make changes in the code, but I don't see any changes on the frontend. Is there some kind of server cache, because when you add a get parameter to the link, the cache is reset and all changes are applied.

If this is not a cache, then what can it be?

Example:

https://higherstatebrain.com/?anyword

ask a question Cloudflare
And so in the browser ctrl + f5 - forced clearing the cache. Of course, if this is not a server cache, but written tags in the server response
