Just to follow up with you, I did check out the 2011 theme and the single events page works fine. Must be something in my theme.
UPDATE: It was a custom function that I had written a while back to enable breadcrumbs to work the way I wanted to with Events. That was causing the issue. All is good now.
Thanks for the reply!
Had the same issue listed above. Changing it from https to http worked for me. Thanks!
