Whenever I open my mini-map calendar to check status of my guilds raid team, I am getting an error message (...Interface/AddOn/Blizzard_Calendar/Blizzard_Calendar.lua:882). I am also recieving a similar error when I enter the guild control tab to edit guild rank priviledges. I turned off all my addons and still the problem occurs. Does anyone have an idea of what causes this and how to fix it?
