Hello. s2Member pro user.
I’m trying to troubleshoot why new registrants aren’t being added to my MailChimp mailing list.
My question: Once I’ve configured my site for single opt-in by using the mu-plugins/s2-mc-hacks.php filter, on the MailChimp side, should I have double-opt in enabled or disabled?
I have left it disabled on MailChimp, but on the S2member settings, I have "Double Opt-In Checkbox Label set, and checked by default “(Yes, the Box MUST be checked)”. However, new users are not being added to my Mailchimp list.
Looking at the log, I don’t see any errors (reluctant to paste it here as it has user data). No mail merge settings are set in MailChimp. Any ideas?
