I’ve got a 1.6.x install running 2 sites via MSM, and I’d like each site to have a different CP theme. I set the preference in Admin > System Prefs > CP Settings > Default CP Theme. The problem is that this doesn’t change anything, since there is also a member-level CP Theme setting under My Account > Customize CP > CP Theme, that overrides the “Default CP Theme” setting. Finally, choosing the “Default” theme setting doesn’t honor the site’s CP Theme setting, since it’s referring to the theme called “Default”.
How can I eliminate member preference in regards to CP Themes, forcing members viewing the CP to be subject to the site’s CP Theme setting, not their own setting in member prefs?
