Hello,
The Mailchimp signup form has stopped working on a site I've been working on.
When you try and submit a form, a 500 (Internal Server Error) is created. If I preview the response this error creates with a web inspector, I get a page with the words: "Cheatin' huh?".
What is happening here and how can it be fixed?
One thought I had was that there was no API key associated with the plugin - I wasn't the one to set this plugin - and so I've created one. However, I can't see anywhere in the admin section where I can enter (or modify the API key).
I'm using the latest version of the plugin: 1.4.1
Any help would be much appreciated.
