Plugin installs fine but project activity tab is broken

[drvora]

We have a bitnami redmine 3.0.2 installed. We have installed plugin using following steps:

1) Download zip file

2) unzip in plugins directory

3) Run commands, $ cd apps/redmine/htdocs $ bundle install --without development test postgresql sqlite --no-deployment $ bundle install --without development test postgresql sqlite --deployment $ ruby bin/rake redmine:plugins RAILS_ENV=production

4) restart redmine.

It installs fine but when we create a project (with or without Jenkins module enabled) it breaks the activity tab of the project. And we get following error in production.log

Is there any workaround for this problem? We can't seem to figure out what the cause is. Our users really want this plugin working for efficient development collaboration. Thanks in advance.

@drvora @n-rodriguez Got the same problem. I've got an 404 error when i try to access the Jenkins tab. The jenkins Tab = translation missing : fr.label_jenkins I can't access to the activity anymore
