Not reproducible on latest 2.2.

The permissions were the reason (example for CentOS):

ls -l /var/lib/php
drwxrwx--- 2 root apache 4096 Nov 24 15:20 session

If I need to change the user group, I must correct permissions to the session folder also.
I believe, it's a good idea to add this note to the documentation.

The issue was caused by Apache not being able to read session file due to change of user group it is running under while setup.php was being used.

Problem did not exist in 2.2 as then intermediate data was stored in a cookie (yes, indeed), and not in session storage (which is files by default).

It might be a a good idea to add some message explaining this behavior in documentation - e.g. if user or group used by Apache web-server is changed, permissions to session files should be verified to be accessible.

Apparently this same issue can have a different cause. I'm using Ubuntu 14.04.01 LTS (server). After trying every "tricks" I could remember, without success, I decided to start tweaking php.ini session parameters one by one.

I found that when you have changed "session.name = PHPSESSID" to "session.name = SOMETHINGELSE" you will have this same problem.

for the record, i could not reproduce the problem with session.name in php 5.5.8
