Issue

• Navigating back, then forward, might causes loss of config data

• Open Jenkins Global Configuration /configure, with the Chrome browser (Firefox does not show this problem).

• Click the back button to navigate away from the config.

• Click forward to go back to the config.

• Some configuration like the Tool installers might be lost.

Environment

• CloudBees Jenkins Enterprise
• CloudBees Jenkins Operations Center
• Jenkins

Resolution

Unfortunately, for the moment there is not a good workaround for this. Basically, JENKINS-18435 needs to be fixed.

You might want to use Job Config History plugin and do periodical backups of your Jenkins instance to get a quick recover in case you are facing this issue.
