Are you having weird issues associated with sessions using Rails 2.3 and Passenger? Perhaps you have problems like repeated flash messages and the inability to logout by destroying a session variable.

There is a simple fix: upgrade passenger. This lighthouse ticket has some more details about session problems.

To upgrade passenger:

sudo gem install passenger
passenger-install-apache2-module

After installing the new Passenger Apache module you will probably have to edit the httpd.conf to include the new version of the Passenger module.

After restarting Apache everything was working correctly.
