Hi Girls!
It could happen when guests try to RSVP on your wedding website they get a screen with to get in they have to fill in a password.If this happens:
You have to go to your Wedding Website. Than click on Settings. Later on go to Passwords and unlock it. You have created and activated a password. So at this moment only visitors who know the password will be able to access your website. If you unlock it, your guests will see your Wedding Website. Now it's private.
I hope this helps.
