have you followed the tutorial? In the page Module Setting, you have to paste the options in this way:
- Mailchimp url form: http://winnerswebdesign.us6.list-manage.com/subscribe/post
- Mailchimp: value u: 6d8c008303
- Mailchimp: value id: 6cea8d2a77
About the contact form, what email provider do you use? Gmail? If you want, you can create a new user for me in your admin panel. In that way, I can check the code. I have done this with other users and there were no problems. You can trust me.
