Help: 500 error page instead of stack trace even on own machine

Hi everybody,

my problem: Since yesterday, even running in development, and from the same computer where the server is running, I always get the 500 error page instead of the detailed stack trace, making debugging really hard.

solutions I've tried: - switching servers (mongrel instead of webrick) and ports, restarting etc - clearing old session - setting config.action_controller.consider_all_requests_local = true in the development.rb config file - even overriding some internals of ActionController

Nothing worked, any other ideas?

Could installing a plugin (paginating_find) or gem (loginGenerator) possibly be the reason?

Thanks in advance for any help, Elmar Schraml
