booking formular issue

Hi,

What do you want to change and how are you trying to save the changes?

sorry I meant the login formular. I want to activate the following fields:
lastname, firstname, email, no phone-number. How do I do it?
Thank you !

You’d need to create a custom version of the file below:

/events-manager/templates/forms/bookingform/login.php

This tutorial explains how to create custom templates that are upgrade safe:
