Hi Don,
Somewhere in your upgrade process you missed the step to remove and then reinstall the mod.
Its a simple process. Just go to the Admin,
Modules -> Order Total -> Local Sales Tax, make note of your settings there and then uninstall the mod (just click the remove button at the top). Dont worry, you wont loose your tax data. Once its been uninstalled, reinstall it. You should now see the debugging options in the admin.
Hope that helps.
Have a good weekend.
