Migrating password in "Password Protect".
How do I erase the "Password Protect This Page" password so it doesn't keep migrating to other pages and returning once deleted from my original page where it was needed? I've repeatedly deleted the password, saved and published. The password not only reappears, but it has migrated to other pages. After performing the remedy several times, multiple times on each page affected and deleting it from the original page several times, I think it's finally been killed off. How can the password migrate to other pages and why is it so difficult to delete?
