Greetings to the Community. I've been developing with SilverStripe in the past on 2.4 and have recently started a project with 3.0

I've downloaded and installed the Multiform module to be able to create a 3 step form.

Problem is that the form does not get past step one. When I press the next button, page reloads and nothing happens except for the change in the URL
from
enoturismo/index.php/marcar/
to
MarcarVisitaMultiForm?MultiFormSessionID=5142d255e209286357b2e8099609e241ce3e0fc9

The Controller is set like the Tutorials advise and I have all the steps classes correct.

Aditionally there's no DATA field saved on the DB for the first step either

Can someone please help me. This is urgent as the projects due date is Friday

Thank you so much!
