Enabling CSRF Protection for Mailchimp Subscribe plugin and other forms
Enable CSRF protection in your config again and add {{ getCsrfInput() }} right after the &lt;form&gt; opening tag on all forms on your site, regardless if they are amforms or mailchimp subscribe.  I can verify that it won't interfere with the mailchimp plugin as I am currently (and just recently) installed it on a project I'm working on and it works fine.
