Activity for Dawn

I have tried and my guests have tried to go back in and change their RSVP or their menu choice but the website doesn’t allow it. This is through weddingwire. Does anyone have any suggestions on how to fix this. I have a message in to the weddingwire...

My guests keep telling me every time they click a new link on the website it brings them back and makes them input their email and name again. It there a setting I need to change so they can navigate freely after inputting their info the first time?...
