Hey Pearl, when you say “we would expect that our plugin would be compatible”, does that imply that anyone has done some testing? I see that the plugin hasn’t been updated in a while. So what’s the most recent version of WordPress that the plugin has been tested with? Our site is currently running v3.6, and the latest version appears to be 4.8.1. As I mentioned in my first post, I’m a WordPress & MailChimp newbie, so I don’t want to do anything that might break the currently-working site.
Thanks again, -Paul
