@arminunruh I am also trying to add an email capture form via Mailchimp. I was able to get the shortcode copied into the gridder but when I test out the email capture I get an error message; "something went wrong. Try again later." I am not trying to add this into the footer so I thought it would be easier.
Is Mailchimp compatible at all with Laytheme? Or is this an issue on the Mailchimp side perhaps?
