rails 3.2 development mode is not displaying the full error page with backtrace etc

Question

I just upgraded to rails 3.2 Everything is working fine except error pages no longer show the normal development debug info. Instead it's showing the standard production error page (white background with red text in the middle:

"We're sorry, but something went wrong. We've been notified about this issue and we'll take a look at it shortly."

Is there a new setting or something I'm missing for rails 3.2? I've read over the upgrade instructions and do not see it mentioned anywhere. I tried downgrading to 3.1.3 and the error pages work again so this is definitely a rails 3.2 issue. Thanks.

Answer 1

Check the config.consider_all_requests_local inside development.rb. It must be set to true in order to show full error reports.

Answer 2

Nicolas, I'm faced the same problem and only saw the message We're sorry, but something went wrong. and nothing in logs.

The problem was in UTF-8 characters, so adding encoding declaration to the beginning of the file solved it:

# encoding = utf-8
