I’m trying to create an opt-in form for mailchimp using convert plus, however, when I input a new email address (one that isn’t already subscribed to a mailchimp list, I get this message: “There appears to be an error with the configuration.”
I’ve been searching through the forum and reading what other people have said and what y’all suggest. I checked the merge fields, and I think they’re correct. Any idea what’s wrong?
