Calendar Error - not loading correctly

Hi all,

I'm having an issue with the calendar module. When you go to click on an event on a certain date on the calendar, it will take you to the events for that day. If you click on the name of the event from there, it pops open a little window and begins the process of loading the info for that particular event, then re-directs to a blank page and stops.

Is there a way to adjust this so that it doesn't re-direct, but just displays the info like it should?
NOTE: calendar is only visible to registered users. Feel free to make an account, fill in all fields with "test" and I'll delete it afterwards.

The site in question is www.scrappersplayground.net/scrapps.

There is also a secondary issue where the login expires for users from time to time for no reason, causing them to login twice. The who's online block is up on the main page to demonstrate this issue, should it arise again.

As always, any/all help with the matters at hand is greatly appreciated.
