Calendar not working for existing users.

I am a ML server newbie. I just installed it (or any OSX server for that matter) for the first time over the weekend. I am setting up a wiki for an upcoming project. I have the wiki working and got all of my content working and got the wiki calendar and personal calendars working. Then I went to subscribe the calendar on a ML client. It took a very long time to add the account and eventually errored out.

After this happened, I am not longer able to view calendars on the wiki or the user profiles. If I try to access a user calendar I get a "too many redirects error" in my browser. If I try to access the wiki calendar I get an application error saying "Unable to load calendar, because an error has occurred." The strange thing is, if I create a new user I am able to access his/her personal calendar and subscribe to it just fine. This does not, however work for wikis. Anyone have any thoughts or suggestions on where to start?
