Payment will not go thorugh

we have a Gravity form that collects payments with stripe. Today we uppdated the form with som new fields and structured the form with pages. Now the payment wont go through…
We have therefor updatet both the main plugin and the Mailchimp add-on(but not the cupon add-on). In the system status we hva an alert on wordpress:

What can be the problem? this is 0 cost course, for testing.

In the log for Gravity + Stripe it says “Empty Token”
