Hey Susanne Knoll,
Please note that we did not create or host your site, we created the theme that your site uses.
Nonetheless, when I test your contact form it seems to work correctly:

Since you are using an old version of the theme (v4.1.2) you should update to v7.1.1
To update your version of Enfold you will need to download the latest <strong style=’color:#000′>installable WP version from your Theme Forest account and upload it to your <strong style=’color:#000′>WordPress ▸ Appearance ▸ Themes ▸ Add Themes ▸ Add New

after you choose the zip file and click install, you will see a <strong style=’color:#000′>This theme is already installed message because you are updating, you can continue

then you will see the <strong style=’color:#000′>Theme updated successfully message.

I also see that your updates are disabled, so if you don’t have a theme forest account you will need to purchase a new license. Envato (Theme Forest) handles all of our licenses and we can not create licenses and Envato will only recognize account owners, this sometimes happens with a site is built by a developer who in the future can not be found, Envato will not issue a new license to the website owner, one must be purchased. The upside to this is that by purchasing a new license you will also get 6 months of support on our forum to help with any issues. I recommend upgrading to a full year of support for just a little more, as the cost of the theme and a full year of support costs the same as a single hour of support from many developers.
Then you can register for our support forum and open a new thread. You have asked your question through the contact form which is not for support requests.
Thank you for your understanding.

Best regards,
Mike
