Thorsten Scherler added a comment - 2018-06-18 17:41 It seems that the resources are not loaded. That should have been fixed with https://github.com/jenkinsci/jenkins/pull/3380/commits/db47e32ad73c27e7aee33676759eb482f22b7eea Can you please open the network tab in your dev tools and let us see whether the css is loaded.

Tobias Gruetzmacher added a comment - 2018-09-18 11:26 I can reproduce this in LTS 2.138.1: Styles and scripts are loaded from the root of the webserver, even if Jenkins is installed in a sub directory (throwing 404s)

Allan BURDAJEWICZ added a comment - 2019-03-21 05:52 tscherler I am able to reproduce this, the browser console shows: /css/simple-page.css:1 Failed to load resource: the server responded with a status of 404 (Not Found) /css/simple-page.theme.css:1 Failed to load resource: the server responded with a status of 404 (Not Found) /css/loading.css:1 Failed to load resource: the server responded with a status of 404 (Not Found) loading.js:1 Failed to load resource: the server responded with a status of 404 (Not Found) (index):3 Uncaught ReferenceError: safeRedirector is not defined at (index):3 loading.css:1 Failed to load resource: the server responded with a status of 404 (Not Found) simple-page.theme.css:1 Failed to load resource: the server responded with a status of 404 (Not Found) simple-page.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)

Allan BURDAJEWICZ added a comment - 2019-03-21 23:42 I believe this is actually a duplicate of JENKINS-55062 now fixes since 2.157.
