Switch Api Key Issue.

Hi There,

I have a local WordPress environment with MailChimp4Wordpress plugin installed. I have two MailChimp accounts one is for testing and the other is for publishing.

I added a sign up form by using the api key of the testing account to my page and it works correctly, I received the subscription confirmation email and I could subscribe to a list of the testing account.

Then I switched to the publishing account by change the api key. I also renewed the MailChimp list and reassigned the list to subscribe. However, the signup form didn’t work anymore. I didn’t receive any confirmation email.

I had tried to use a new api key of the publishing account but it didn’t work.
I had switched the api key back to the testing account and it works.

Did anyone ever met the same issue? Since the api key is the only thing I had changed, I’m wondering if the issue has anything to do with the account settings.

Thanks!
