I have an existing Webflow site as well as a Mailchimp account. I have a form already on my site collecting emails, but for some reason, the form broke, and I cannot get it to work. It used to work, so when people entered their email on my site on the pop-up, it just went to my Mailchimp list. But for some reason, it won't work now, and I just need someone to take a look and fix it quickly.
