Payment will not go thorugh

Hello
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… https://www.anncathrinshundekurs.no/bestilling/?kurs=Hverdagslydighet5#gf_7
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?

https://www.anncathrinshundekurs.no/bestilling/?kurs=Hverdagslydighet5#gf_7 this is 0 cost course, for testing.

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

Please open a support ticket here for your issue and we’ll help you out where we can:
