Error copying date from event post type

Hi there,
I have some questions:
1. I would like to have selected sites post to a DEFAULT target site so the users won’t have to select a target, all events should be copied to that target site automatically.
Is there any way to do that?

2. Coyping works fine but when I try to look at the copied event, it throws this error :
Error in formating DateTime object. Expected DateTime, but instead given boolean
I FOUND this solution from the developer of the event plugin:
Support Topic event organiser but I don’t know how to trigger that code mentioned there. Can you help?

Thank you very much!!!
Regards
Anja
