  • Hello, Check in your Vhost
    Replace AllowOverride None
    by
    AllowOverride All
    I just check this exatly causes the situation you describe above.
    Do not forget to restart apache afterwards.

    • Up: If you do not have this directive in your Vhost, you can also change it more general way instead of doing it for a single site
      In case you are on Ubuntu, edit the file /etc/apache2/apache2.conf (here we have an example of /var/www):
      <Directory /var/www/>
          Options Indexes FollowSymLinks
          AllowOverride None
          Require all granted
      </Directory>
      and change it to;
      <Directory /var/www/>
          Options Indexes FollowSymLinks
          AllowOverride None
          Require all granted
      </Directory>
      then,
      sudo service apache2 restart
