Hi,
I have little bit different problem with “page not found”. when I add some events i can see those in the calendar, but when i press on those to get more info I get message what the page does not exist. On a edit events menu its looks ok but when I try to make preview i get the same page not found message. I know it has worked before so now it start to be the pain in my ass to find what the hack its going on.
