title: Cannot access superuser in Django admin page created by python manage.py createsuperuser
body: <p>When I create the superuser in Django, which runs successfully, when I try to enter in the admin path in my browser <a href="http://127.0.0.1:8000/admin/login/?next=/admin/" rel="nofollow noreferrer">http://127.0.0.1:8000/admin/login/?next=/admin/</a> and insert the email and the password, I get the following error:</p>
  <p><strong>Please enter the correct email and password for a staff account. Note that both fields may be case-sensitive.</strong></p>
  <p>Can you help me? I don't understand where is the problem.</p>
  <p>I have defined the following fields in the Account models.py file:</p>
  <pre><code>is_active = models.BooleanField(default=False)
  is_admin = models.BooleanField(default=False)
  is_staff = models.BooleanField(default=False)
  is_superuser = models.BooleanField(default=False)
  </code></pre>
