title: How to fix broken images and icons in jenkins UI
body: <p>I am having trouble with the jenkins ui these days with all the images and icons (build icons and those in the manage jenkins page) broken. I have googled and haven't found anything clear. Also, the jenkins became much slower. I read that clearing the TEMP folder might cause this issue. and yes after restarting the jenkins service on the instance it has become much worse and all icons were broken. How can I fix it? Screenshots attached Can someone help me with this.
