Hi,
After a few months of successfully working, today my Mailchimp footer signup is delivering this message: “We’re sorry! Something went wrong. We were unable to add your email to the list. Please try again later.”
I had an initial surge of people sign up to my list on Black Friday (100+), and nothing since then, so I would guess it stopped working this weekend. We have not changed anything in the backend so it’s a bit of a mystery.
