The "gear" icon / "configure" icon on a Job should take me to the Jenkins classic configuration page for the job.
It currently takes me to a broken URL in Jenkins classic as it assumes a "/jenkins/" prefix
1. I am viewing "/blue/organizations/jenkins/pumpkin/activity"
2. I click on the "gear" icon (left hand side, next to favourite star) - check all gear icons - as they're "all" doing
3. I am taken to /jenkins/job/pumpkin/configure
1. I should have been taken to /job/pumpkin/configure
