I saw this when searching on the forums (from a couple of years ago)
so I uploaded the appropriate files to my server and installed the add-on. The add-on works in that the installation went fine and I ensured it was enabled, then I attached my Mailchimp API key and suddenly, on registration, New Users are now confronted with a 'signup to newsletter' box that is automatically checked by default..
However, on testing it by registering as a new dummy user, the user registered fine to the forum...
but the user was not logged on Mailchimp at all. The list on Mailchimp still shows that it has 0 subscribers and 0 visitors.
Perhaps it takes Mailchimp a few hours to update its list of subscribers? but I doubt this.
anyone know what might be wrong - maybe the add on is obsolete in some way?
Any info would be awesome.
