In my app I've started to get a 500 error whenever trying to post to a
create method

/!\ FAILSAFE /!\  Sat Apr 11 18:42:28 +0100 2009
  Status: 500 Internal Server Error
  string not matched


According to the log it doesn't even get as far as the POST

anyone know what might be causing this?

I also have nested resources in my app - when creating one of them
they seem to work fine! ?

here's the full trace from the log:

Are you using Rack? It looks like you might be experiencing this error
(or something very similar):
