Error while access Redmine

Added by George Wei about 15 years ago

Dear ll,

I've installed Redmine 0.8.1. When I access http://localhost:3000, I encounter this error "Action Controller: Exception caught". The detailed information is as follows:

------------------------------------
NoMethodError in WelcomeController#index

undefined method `each' for #<Mysql:0x4a79f8c>

RAILS_ROOT: D:/redmine-0.8.1

What's the output from script/about? (See: http://www.redmine.org/boards/2/topics/667)
