I have just set up Newsletter with its own URL for the newsletter_profile like so:
label="GDPR Permissions: please check this box to confirm you give us permission to email you the Total Carbon Rationing newsletter. Your email address will never be sold or given to any third parties. You may unsubscribe at any time using the link at the bottom of the newsletter email."]
I can see from the URL query string ‘error’ parameter, after submitting a test email address for a second time. But I don’t see the error anywhere.
I understand how most of the plugin works, but I haven’t figured out this part yet. Please can you provide some info?
