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.
