I haven't attended my fledgling websites for a year (had a bereavement), and I had left them marked private. But I when I typed in one URL today the website was found and was visible - before I logged in.
I logged in and found that all the pages were marked private, so I'm baffled. I upgraded WP to the latest version. I searched this forum and subsequently cleared the cache in WP and on my browser. I logged out. The site is still visible.
The same thing is happening with another site I have in development - even my son can see it on his computer - clearly not logged in. There is even a page visible that is no longer available to me as an administrator or by any navigation from the dashboard.
What's this all about? Please can someone help me make my pages private until I want the world to see them?
