None of my password protected pages work after wp upgrade to 3.4.2 today, I enter the correct password and it reloads byt get back to enter the password field.
I have looked through many posts about this back over the years, many have struggeled with same issue. No earlier solutions works for us.
I have tested to deactivate all plugins.
I have cleared cookies.
I have reset all my passwords and created new pages.
Still same problem.
