Hi!
I installed it today, I followed all the described steps and I have the same problem. I did all the procedure indicated here and it did not work.
The problem is the confirmed name/email is not appearing in the “Members” list in the settings, and when I click the “Download CSV” button in the settings, the confirmed email address is not there! All I see is “Name” and “Email” in the table.
In phpmyadmin I also only see the table: “wp_email_capture_temp_members” and the table does not appear “wp_wp_email_capture_registered_members”
Thanks!
