By default, RSVPify allows for editing of all submissions with an exception of paid ones. Guests can make edits to their submissions in several ways. With that said, we also allow event hosts to disable the submission editing ability. Here's how:
Step 1: Customize > Event Settings > Security & Passwords
In your event's left navigation menu, locate Setup and from there select Event Settings. In the Event Settings page select Security & Passwords.
Step 2: Toggle off the ability for editing submissions
Under Registration Edits & Cancellations section, toggle off the button for editing submissions. By doing this, your guests won't be able to edit their registrations.
Step 3: Save the changes you made
