How can I change the title in the Jenkins start page: http://jenkinsserver.domain.whatever:9090/
As I see, the title is already in German with some special UTF-8 chars and this one makes trouble using selenium in the background to control Jenkins. I am quite sure the value is set somewhere - but where?
Jenkins runs on a Windows server.
You can just install the Simple Theme Plugin and then in Manage Jenkins > Configure System > Theme, point the URL of theme JS field to a .js file containing at minimum something like:
document.title = "Wathever title you prefer";
Save and reload the page.
It worked for me..
