Application error

[todo01]

the page display this message..:Change this error message for
exceptions thrown outside of an action (like in Dispatcher setups or
broken Ruby code) in public/500.html

i have search the group and found this solution :

Session.create_new_id has become Session#create_new_id
(http://tinyurl.com/5j7nx). This was reported on Nov 27
[ruby-core:3832],
and fixed on Nov 29 (http://tinyurl.com/3pvrw).

Ahh, okay. So if people see this error they'll have to apply
http://tinyurl.com/3pvrw or update to the CVS version. Gotcha. Thanks!

i still get the same error message,,,why?
the apply means this ?

fault..

and can't go on now...
