The forms are not working.

Good afternoon. I have updated the license for the forms on the website https://www.besinspain.es.
The contact form is not working.
Please go here: https://www.besinspain.es/allcategories-es-es/categoria-es-es/contacto
If it's not too much trouble, could you please check what the problem might be?
