I've been trying to fix a bug in the Rails app I'm developing, and I keep getting a blank screen with no errors. I haven't found anything helpful in development.log, either (though it does show queries being run and such).

Finally, I started to wonder if it's somehow set not to show errors anymore. I tried commenting out a necessary route, and sure enough, I got a blank page instead of the error and stack trace I expected.

What might cause this?

(I wondered if maybe I'm accidentally running production mode and errors aren't supposed to show then, but development.log is being appended, and if I open script/console and echo ENV['RAILS_ENV'], it says development.)
