Not possible to create event feed

hi there,

it is not possible for me to create an event feed. This error occured:

There is no data matching your choice..

After 10 times clicking the save button I have another error on the page:

There are no objects in this facebook feed.

All the other feeds are working. Only the event feed is not working. I already tried other fanpages and it also didn’t work.

I already inserted the App details but it still doesn’t work. Also it doesn’t work to login into facebook with the app. It says that the domain isn’t in the domain list of the app. But it is. Any help?

The page I need help with: [log in to see the link]
