Remove items from K2

Hi
I use quick start and now I want to delete, unpublish or for example change category some items.
When I do so I get an error message, see file.

Can't I change anything about the items in K2?

Hi,
probably that's why - that some of modules uses this content which doesn't' exists anymore.

Try to change default home page to another item.

I always suggest one thing:
Use Quickstart as a playground only and empty joomla with our template + modules as a real construction site.
No trash/demo content = no problems.
