Start error: uninitialized constant MessageObserver (NameError)

Added by Petr Frank about 4 years ago

Hello all,

i've just spent many hours to get redmine working but without success. That's realy hell. I've tried approx three "how to" (some from your wiki some from another users) but i'm still ending on any error during start. Some errors i fixed regarding experiences of another users by googling but this error is my total stop. I can't do next step.

Does anybody know how fix this error? Does exist any painless installation procedure for Debian Wheezy? I'm realy on the ond of my sources.

Error page with all details attached.

Thanks for help.

You probably trying to upgrade previous version of redmine?
Try to comment out a line in file config/application.rb

config.active_record.observers = ...

but proper way of upgrading redmine would be: use newer config files.
