9908	TeamCalendarPlugin works partially	gmanukya@…	Chris Nelson	"Hi,

I have instaleld TeamCalendarPlugin and edited the trac.db with sqlite3 as instructed. The new tab ""Team Calendar"" showed up on the top right corner as promised. 

When I go there and select the dates for users then I click ""Apply Changes"" button I get the following error message:
