Redmine

Hi there,

I tried to install the last release of the redmine timesheet plugin (the fork by Hisham Malik) and I have a problem with my new Redmine 2.2.0 installation.

I copied the plugin :
git clone git://github.com/techarete/redmine_timesheet_plugin.git plugins/redmine_timesheet_plugin

Bundle install is ok.

rake redmine:plugins:migrate RAILS_ENV=production is ok

rake tmp:cache:clear is ok

Restart redmine and I have a 500 error while I try to access the web site. Here are log information withing the production.log file :
