Hello
First of all thank you for that great product! I have successfully installed an instance of openproject 3.0.8 on Ubuntu 12.04 with MySQL as the database. Additionally I installed the plugin backlog. I can see the plugin in the administration settings and access it’s settings. However when I try to access the backlog page in my project, I receive a 500 error. What could be a possible cause for it?

I run the instance under the rails server command as a daemon in production environment. I have successfully run the rake db migrate command with ruby env production. I cannot find any corresponding entry in the production.log (in fact nothing is written into it when I try to access the page). My Gemfile.plugins:

gem “openproject-plugins”, :git => “https://github.com/opf/openproject-plugins.g
it”, :branch => ‘stable’
gem ‘openproject-pdf_export’, :git => ‘https://github.com/finnlabs/openproject-p
df_export.git’, :branch => ‘stable’
gem “openproject-backlogs”, :git => “https://github.com/finnlabs/openproject-bac
klogs.git”, :branch => ‘stable’

Thanks for any advice!
