`         


        

Answer 1

Syck is a Yaml parser, so maybe you have an error in one of your Yaml files? Locale files or your database.yml are good bets.

Failing that, make sure that the yaml parser is using the correct yamler by adding the following to boot.rb:

require 'yaml'
YAML::ENGINE.yamler= 'syck'
