Forminator: your form is not valid

Hi,

I created a simple submission form (name, address etc) that should send an email to our ‘info’ mailbox. Nothing fancy or complex.

But despite all fields being filled out, Forminator still returns a generic error “Your form is not valid. Please fix the errors!” without even telling me WHAT the error is…

All fields are set as mandatory, and all are filled correctly.

This is the form code
