Hi @icu1274
We’re sorry to hear that you have issue with our plugin.
We’d need more details about this error in order to reproduce it on our test environment.
What are you doing exactly when this error happens?
What screen are you viewing?
Have you double-check your API Key in General settings?
There isn’t actually any WP_Error thrown by our plugin so it must be a conflict or wrong step in our coding when decoding MailChimp API’s response.
We have just released a new version 2.0.2 which should fixes your issue.
Could you please update or delete then reinstall MailChimp Campaign Displayer and let us know how it goes?
Hopefully you will be able to display your newsletter without more effort.
fix is 2.0.2.1 😉
let us know if its ok now.
cheers!
We mark this issue has closed as it seems everything is working fine for you now.
