I'm running a local Linux controller, using the tarball distribution (not deb). I just upgraded my controller from 4.2.0 to 4.4.3 using the "uninstall.sh upgrade" method and everything seems to be working, except when I go the Site Configuration screen. I can save changes on other settings screens without any issue. But on the Site Configuration screen, if I change anything and click Save, I get a "General Error" toast. In the controller logfile, I see this error:
