Multisite privacy plugin is not working on 2 sites created with Cloner

I can’t access two sites I’ve created using Cloner in my multisite. Multisite Privacy is not working. It shows an error message if typing a wrong password, but it’s not doing anything when typing the correct one. It’s recognizing the password, but not opening the page (I've tried using another pwd and I got an error message, but when using the correct password it just doesn't do anything).
