Just to specify:
The Error is happening in our Newsletter Popup (Made with Popup-Make, the form is by Ninja Forms 3 with the Mailchimp Integration via your mc4wp plugin)
The Popup is triggered automatically after 2s. If you dont see it check your cookies (pum-2997/pum-2998)
Thanks a lot!
Hey Danny,
thanks for the fast reply.
Just had a look at the version, Version 4.1.12 is live.
The Double Opt In E-Mail is still not sent.
Thanks for your help.
Kind regards,

Just rechecked: Subscribing works, Double Opt In does Not work… ☹️
