 * Hi,
 * I get the same issue. I have used this for a fw months and worked great. however
   last week a got loads of failed to subscribe emails. This resolved itself but
   now when setting up a new site my API key isn’t being accepted.
    Looking on the
   website it says
 * “IMPORTANT: You must upgrade to version 2.X by December 31, 2016 as prior versions
   of the MailChimp API will stop working at that point.” On the offical plugins
   page I have the latest version.
 * Please can you help. I seem to be able to still sign up new customers when they
   opt in even though the API says failed but i can’t select the groups etc.

 * I’m using this plug-in successfully for a long period, but it stopped as of today
   on the same error.
