[xwiki-users] Exception when saving update to a page

Hi, I am a user of myxwiki (http://crindau.myxwiki.org [1]) and tried to edit a page (adding a link to a page I was about to create). On clicking on "SAVE & VIEW" I got the following: Detailed information: Error number 3201 in 3: Exception while saving document crindau:Diary.August 2012 Wrapped Exception: Error number 13012 in 3:
