Some Jotforms don't work

Dear,

I just noticed that some of our Jotforms don't functionate anymore.
For example:
https://royalbrinkman.com/promotion/featured-products/bumblebees-in-greenhouses
https://royalbrinkman.com/promotion/featured-products/greenhouse-roof-cleaners
https://royalbrinkman.com/promotion/featured-products/crop-rotation-machines

We don't know how this is possible. 
Could you please help us out?

With kind regards,

Jeff Zuidgeest

We’re sorry for the inconveniences. We have a temporary problem with our system.

We’ve fixed the issue, all of your forms are working without any issues.

Please check and let us know the problem still exists.

Thanks.
