I have a password protected page which I recently was asked by my client to change the password. The password protection is done from the WordPress dashboard by using the Status and visibility option from Page-> PageName -> Edit option and selecting Visibility: Password Protected and editing the password. The previous password had worked fine for many months but once I changed the password, the new password was not accepted. I keep getting the prompt for the password no matter how many times I enter the correct password.

Cache busting or a clue?

Interestingly if I add a cache busting querystring like ?a=0 to the end of the protected page\'s URL, I am let in! What\'s up with that? Does the page/WordPress know that I previously entered the correct password?

With WordPress, does the user need to enter the password each time they visit the password protected page or only the first?
