Requiring new user email validation

I have a problem with new user registration with email validation.

Steps I took leading up to the issue

  1. Set require_validation = On (SMTP mail configure already successful)
  2. Click on ‘Register’
  3. Fill the registration form
  4. Click ‘Register’
    => The user has been registered to the Database, but the confirm email was not sent to the user’s email.
  • When I debug the error the variable of $address & $name not get value after user submit the form in __construct of lib/pkp/lib/vendor/symfony/mime/Address.php

What application are you using?
OJS 3.3.0-5
Theme: Health Sciences Theme
PHP 8.3
Ubuntu: 24.0
