We tried adding it to the child theme functions file but it resulted in a white screen…
MS doesn’t specifically say put it in the header file
“We recommend that you paste the form code to a Post or Page, because WordPress elements like footers, navigation bars, headers, sidebars don’t always support this type of embed code. To use a subscriber popup form, you may need HTML experience, or access to a developer or MailChimp Expert.”
So if I was to add it to my home page would I use the “Raw JS” page builder element?
Many thanks, Nicky
