I'm having trouble deleting Nagios XI host, I went to Core Config Manager,
I would delete the Services and Host, but when I go back to Host Details,
I would still see the host.

This seems to be intermittent, was wondering why?

You could be running into ghost hosts, which is an odd anomaly. The resolution is posted here:

that solved it, thanks
