After installing eZ Publish 5.0 beta2, I'm still redirect to /ezsetup. There I am given a login page, not the frontpage I expected. If I try to login with my credentials nothing happens.
In the ezpublish_legacy folder, inside var/log/error.log I got the following:

If I use index_dev.php instead of index.php the Symfony bar doesn't appear, even if I manually delete Symfony cache.

Steps:

1. Install eZ Publish 5.0 with eZ Demo without content
