https://jenkins.logilab.org/blue/ show the list of projects, but no info on the projets except for two projects (click on show more to see those). Clicking on the projects that have summary info shows correct pages :

https://jenkins.logilab.org/blue/organizations/jenkins/jenkins-jobs/activity works

All other projects shown an empty page :

https://jenkins.logilab.org/blue/organizations/jenkins/cubes-datacat/activity doesn't show anything (undefined/undefined in title)

https://jenkins.logilab.org/ default UI shows the jobs have been run (in most cases at least one).

by the way : kudos for a great interface, looks promising!
