[xwiki-users] Calendar Trouble

I have been trying to enter a new event in the calendar on the EventCaledar page only to be given the message below. I only have the one page open, no one else is editing the page (at least not one that is owning up to it), and I am logged in as administrator. I can't seem to get what I am doing wrong. please help! Thanks! Warning This request contains an invalid authentication information.
