Error message when loading website + Domain authentication

Hello!

I have an issue I need sorted asap.

I am using Mailchimp and tried to update DNS name servers for domain authentication. This was confirmed as done in Mailchimp.

After doing this my website now won't load. Please see error message. My website is built on WIX and hosted on Wordpress. I deleted the new DNS name servers from Wordpress but this hasn't helped.

Once this is fixed, I would also like to transfer the domain to WIX so I have it all in the one place.

Thanks
