Redmine

I managed to install the schedules plugin on 0.8.2 version of redmine, without any problems initally. The problem that I have is that once i update a the schedule for any project I get an internal error and can no longer access the schedules page. I have updated to 0.8.3 but this doesnt resolve the issue.

The log file shows this error:

ActionView::TemplateError (Translation value "%.2f hour" with arguments [{:value=>8.0}] caused error 'can't convert Hash into Float') on line #2 of vendor/plugins/redmine_schedules/app/views/schedules/_schedule_entry.html.erb:
