Check for a static version of your page in  public and delete it if it s there  When Rails 3 x caches pages  it leaves a static version in your public folder and loads that when users hit your site  This will remain even after you clear your cache

This line in development rb ensures that caching is not happening   config action controller perform caching               false   You can clear the Rails cache with   Rails cache clear   That said - I am not convinced this is a caching issue  Are you making changes to the page and not seeing them reflected  You aren t perhaps looking at the live version of that page  I have done that once  blush    Update    You can call that command from in the console   Are you sure you are running the application in development   The only alternative is that the page that you are trying to render isn t the page that is being rendered    If you watch the server output you should be able to see the render command when the page is rendered similar to this   Rendered shared partials  latest featured video  31 9ms  Rendered shared partials  s invite friends  2 9ms  Rendered layouts  sidebar  2002 1ms  Rendered layouts  footer  2 8ms  Rendered layouts  busy indicator  0 6ms

If you re doing fragment caching  you can manually break the cache by updating your cache key  like so   Version  1   lt   cache   cool name for cache key    v1   do   gt    Version  2   lt   cache   cool name for cache key    v2   do   gt    Or you can have the cache automatically reset based on the state of a non-static object  such as an ActiveRecord object  like so    lt   cache  user object do   gt    With this   method  any time the user object is updated  the cache will automatically be reset
