Hi! I paid, with my creditcard, the fee for the Global Art Fair in Amsterdam 2019. Everything went smooth until I should finalize it, then the webpage couldn't be found, and I don't know if the money reached the GAF. But it is taken from my account. 

The URL I can see now is https://www.2checkout.com/checkout/purchase 

now is https://www.2checkout.com/checkout/purchase

It looks like that you have submitted the form http://www.jotformpro.com/form/80863199875980. Since the form is being managed by one of our users, we request you to check with the form owner for the payment related information. They can provide you with the information about your payment. 

Thanks!
