I'm trying to use the Mailchimp Campaign Archive plugin, but it seems to conflict with the Mailchimp sign up form plugin. I am getting this error from the archive plugin:
Fatal error: Cannot redeclare class MCAPI in /wp-content/plugins/mailchimp-campaign-archive/mailchimp-api-mini-class/MCAPI.class.php on line 3
This plugin is just what I need. How can this be fixed?
