We are using the Pro Email Forms Add. We use Mailchimp.
There are two places on the site that use the forms.
Homepage: https://getboober.com/ uses [tco_subscribe form="311"]
Once you've filled out the form and click submit, the button goes dull and there's a weird circle with a line through it which makes it seem like the email wasn't correctly submitted. What is more the message that should read "Thank you! Check your email" doesn't appear.
Refer a friend page: https://getboober.com/refer-a-friend/ [tco_subscribe form="1259"]
This form is supposed to redirect the user to https://getboober.com/refer-a-friend-discount/ but nothing happens when you click submit (same as the homepage) We've tried using both shortcodes below and they react the same way.
Mailchimp is correctly integrated - or so I believe.
Thanks for your help!
