Thanks, it is working again.
Yes, I am using Edit Flow. I downgraded the edit flow to version 0.7.4 and now the editorial calendar is working again.
I have the same issue as well. When I drag the post from the sidebar to the calendar, it will work (I checked the Post section and the date has changed as well), but when I refresh, the post went back to the sidebar.
It was fine with the previous version. This only happened after the latest update.
After upgrading to the latest version (0.2.3.1), composing in the text editor becomes very laggy. After I deactivated the plugin, the speed return. What is the cause for this?
