I just installed acts_as_attachemnt_fu and it works on Mongrel and Webrick, but not on phusion passenger.
I am totally stumped, and there is no log anywhere to say what is wrong, just this error :
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there was an error in a CGI script.
Why is this failing on phusion ? Anything specific I need to do ?
