I watched the tutorial and downloaded the editorial calendar plugin. It worked great. Then I added several draft posts. I wanted to schedule some using the calendar. But when I returned to the calendar, nothing worked. The draft posts are listed on the side, but the calendar is blank. No dates, no posts, nothing.
I uninstalled the plugin and reinstalled it, but it still does the same thing. The unscheduled draft posts are listed, but the calendar doesn't load.
