I upgraded Jenkins to the newest version, 2.277.1. I also upgraded our Dimensions CM server client to 14.5.2. After the upgrade Jenkins is not functioning properly. Existing configurations are still working, but I can not make any new changes. The Apply/Save buttons do not work on any jobs/projects. I can't create a new project. I can't make/save changes in Configure System. Within Configure System and inside individual job Configure page, I noticed the dimensions section is now booted far to the left on the configure pages. The top tabs for each sections no longer appear anymore either. I attached screenshots of how the configuration pages are looking.

I went removed Dimensions plugin, restarted jenkins and all the configuration pages went back to normal and worked as expected. The Save/Apply buttons both worked again. I reinstalled Dimensions and it went back to not working again. I tried installing the previous version of the dimensions plugin I had before that worked and now that is still causing the same issues.

This is in my production environment and any issues coming up, any changes needing to be made and any new projects to create, I cannot do and has our development team very locked down and affecting 100s of applications.
