Hi,
when the rename login page feature of the Plugin All In One WP Security & Firewall is enabled,
It becomes impossible to reply to user requests of personal data export or erase.
That’s the WordPress feature that is in Tools -> Export Personal Data or Erase Personal Data.
This features sends an automated WordPress message to the requester, which prompts them to click on a URL with that structure:
https://domain.com/wp-login.php/?action=confirmaction&request_id=%5Bsome number]&confirm_key=[some confirmation key]
The users are therefore never able to verify their request of data export, as they just get a 404.
