Hi
We cannot make any changes in Nagios XI (modifying any services or host information or anything in Core config manage).
It gives this error

Warning: Duplicate definition found for contact 'xi_default_contact' (config file '/usr/local/nagios/etc/contacts.cfg', starting on line 47)
Error: Could not add object property in file '/usr/local/nagios/etc/contacts.cfg' on line 48.
Error processing object config files!

Hello @cmls,

You've got an error in the current configuration. Have you tried restoring a previous configuration snapshot? You can do this by going to Configure>CCM>Quick Tools>Configuration Snapshots. Next, click on the green arrow from the Actions menu to restore.

Alternatively, within the CCM, go to Alerting>Contacts and search for xi_default_contact. Do you have more than one? If so either delete it or deactivate it, and try to Apply Configuration again.
