No Login after upgrade to Rails 2.3?

It cost me some hours on a sunday afternoon. After I upgraded to Rails 2.3.2 the login didnt work anymore. I read the release notes and followed all the instructions for cookie based sessions, like renaming session_key to key in the session config hash but still no luck. Things got more confused because locally everything worked fine. To make it short the solution is really very simple but you dont read much about it: you need to upgrade passenger to the newest version.


gem install passenger

passenger-install-apache2-module


And dont forget to adjust your apache config with the new settings. These are generated by the installer so you can just copy them.
