While performing apply configuration, we are getting below error. Please find attached screenshot for more details.
Please suggest.

* Reset config permissions failed.
An error occurred while attempting to apply your configuration to Nagios Core. Monitoring engine configuration files have been rolled back to their last know good checkpoint.

@Samreen Mardhani, In XI web interface please go to Configure -> Core Configurations Manager, then click on Tools -> Config File Management in the left column. Then perform the following actions in order:
1)Write
2)Delete
3)Write
4)Verify

If you see the same error that the service has no hosts, go to Services in Core Configurations Manager, select the config and make sure that all services have a description and are assigned at least 1 host. If you have trouble with this click on the floppy icon next to any service and send me the "AGILE_WIN...." config definitions in a text file.
