Nagios Support Forum

Hello, Thank you for your help.

I uploaded the file.
Whenever I tried to remove services, I saw the same error.
There seems to be a problem with the contacts.

I have troubles to deleted contacts or services on the web, according to the error message there is a dependent relationship between services and contacts, but i want know if there are any way to cancel those relationships or delete service or contacts on the host.
Could you please help me?
