Mail Chimp - Invalid Mail Chimp Id:0


I keep getting this error when I try to signup to my newsletter. v4.2.3


Dear Kayokoko Swimwear,

Could you please explain in details.

Are you trying to signup to the newsletter as an admin? Or what?

Best regards, Alt-team.

either way via the admin or from the signup field on the site. It give me this error. I have made sure the client ID is right and the correct list is selected in the addon.


Unfortunately, it is hard to give you any advice not seeing the code.

Please contact the CS-Cart support team.

Hope they can help you.

Best regards, Alt-team.
