Yes, I am the admin and sometimes I receive cashed pages but when it happens I use a plugin called “Hummingbird Pro” to clear the cache on demand.
I couldn’t wait for your reply so I created a page in WordPress with the slug name “404-2” and I added to it a redirect to https://google.com at least until I receive a reply from you on how to fix this.
Again, I want when someone tries to inspect my site it shows them a blank page.
