I just installed Drupal 8 using Drush (followed installation guidelines) and the site seems to work fine. I get a home page (probably the default one, no styling). The links like “contact” “login” etc all return 404 (i have mod_rewrite enabled on apache2).
Anyway, even /?q=admin or /?q=user do nothing (200 OK from the apache2 log file) and clean URLs all return 404.
I found nothing helpful googling this issue.
