Hello,
Thank you for your reply, and sorry for my late return!
Indeed, the error lies in the integration of API with Mailchimp (the message is “Only one integration can be used at a time … you pick!”)
Would you know how I can solve this problem to have the 2 email collection lightboxes, connected to my Mailchimp account, on the 2 sites of the multisite?
Thank you,
C.
