The link "Events" in navigation.

[Donuts]

Hello, I've made a website in GS. Created multiple pages and added to the navigation. Al work just fine expect one, the link "Events". Where you would expect the "Events" page, I get a "Page not found" error message. Stange, the pages under "Events" remain accessible if you link directly to it.

I'm using the i18n plugin fot the navigation.

The 404 page: http://www.shiftinglands.com/events/
The strange page: http://www.shiftinglands.com/events/crisis-2012

Who has idea how to solve this?

Greetings Tom.
