All - Every time I try to save the config I keep getting one of the below messages. I'm on the latest version, which I just updated 5.7.2
Error: Contact 'username' is not defined anywhere!
Error: Could not add contact 'username' to host (config file '/usr/local/nagios/etc/hosts/filename.cfg', starting on line 16)
Error: Contact 'username1' is not defined anywhere!
Error: Could not add contact 'username' to host (config file '/usr/local/nagios/etc/hosts/filename1.cfg', starting on line 16)
I tried to edit the config and remove the name but it keeps coming back? I even tried to remove it from the contacts.cfg. These user names are nowhere to be found in gui in contacts either. I even try to do a DB clean up, no good? Thank you for your help
