CONFIRMED: Error does not occur with version 0.3.2

[nateberkopec]

Looks like #104 broke compatibility with Rails versions less than 3.2 (when ActionDispatch::DebugExceptions) was introduced.

@charliesome, is better_errors dropping compatibiilty with Rails 3.1 and less?

I am getting the same error wats the solution

[nateberkopec]

@harsshhfs It's fixed in the repository, but there hasn't been a new gem version since the fix was applied.

To point your Gemfile at this git repo instead of the rubygems version, try:

gem 'better_errors', :github => 'charliesome/better_errors'

hey thanx for reply @nateberkopec
