Cannot disable theme picker in UI16


The process to disable the theme picker (described in the product documentation at does not work in UI16, although it does work in UI15 and UI11. The two UI macros of ui_theme_changer exist because one is for UI15 and the other is for UI11; however, they are not used in UI16.

Steps to Reproduce


  1. In an instance running UI16, navigate to System UI > UI Macros.

  2. Find and select the ui_theme_changer UI macro.

  3. Deselect the Active field and click Update.

    Despite this setting, the theme picker is still active.


To prevent users from changing their themes:

  1. Access all the themes available for UI16 (Concourse) by going to http://<instance name>/

  2. Set all of the themes to active = false.
