AR Sessions Stop working

hello,

For some reason, i restarted mongrel and the AR sessions stopped working. They were working fine before restarting and I did not change anything in the environment.rb file. Any idea why this would stop working? Sessions table still exists all that happened was a mongrel restart to install a plugin.

Any ideas would be great.

Thanks

The same thing just happened to me right now.

Boggles my mind -- Works perfectly locally, but bombs out on
production using RailsMachine

i tracked this down to the acts_as_cached plugin, not sure how. I removed the plugin from the plugins directory, restarted mongrel and everything worked fine.
