I have 2 Lists in Mailchimp. I went into my API settings and created a new API key, and made sure that the API key is enabled. Then I went into my WordPress install, went to WP Mailchimp > Settings and entered and saved my API key there. But when I go to WP Mailchimp > Lists, Vars & Groupings, there are no lists found. And if I go into WP Mailchimp > Auto Campaign (my reason for wanting this plugin), next to Select List is blank. The drop-down doesn’t even appear there.
I just updated to WordPress 4.9, but was having the issues in 4.8 as well. Any ideas?
