I just upgraded from 6.5x to 6.7.1. Since doing that, the "general" section of the control panel under display options no longer works.
What happens is that I can access this section just fine; however, when I click "submit changes," I get a blank screen instead of a confirmation, and when I go back in, the change has not been saved.
The same thing happens with "Primary Settings." All the other elements of the control panel seem to work fine.
