MailChimp WP Integration Issues

Hi there! We have gone through the support topics and haven’t found a solution for the issues we have been having with our MailChimp opt-in form on a client’s website.

We get a success message from the form on the site but an integration error…

*** Service ***
Array
(
[name] => Newsletter – Mailchimp
[url] => http://gla-rehab.us9.list-manage.com/subscribe?u=f3b9edc94ffd19e8c3aa7a81b&id=5dab8cd39c
[forms] => Array
(
[0] => cf7_93
)

[success] => please click the link in the email we just sent you
[failure] =>
[timeout] => 10
[mapping] => Array
(
[0] => Array
(
[lbl] => Email
[src] => your-email
[3rd] => EMAIL
)

[1] => Array
(
[lbl] => Subscribe
[src] => submit
[3rd] => subscribe
)

)

[separator] =>
)

Any help would be awesome!
