I've been setting up the excellent Mailchimp extension from Vedaconsulting.
It all seems to be working correctly (thanks to this page), except for when posting on the fly from Civicrm to Mailchimp:
I've setup a smart group to correspond to a list in Mailchimp. If I unsubscribe someone from Mailchimp then Mailchimp's webhook fires and the person is correctly removed from the smart group.
But if I add someone to the smartgroup they aren't being pushed to Mailchimp. There is immediate activity in the Civicrm log, but the name of the person isn't included. (Arrays contain info about the list and groups etc, but not the person.) And no change in Mailchimp.
Nevertheless, syncing Civi from/to Mailchimp seems to be working fine.
What could I do to troubleshoot this?
We're on Drupal 7.50, Civicrm 4.6.17, Mailchimp 1.8.7. Our server is locked down pretty tight... but if syncing is working then I would have thought the database post should be working too?
Thanks for your help!
