Reading configuration data…

Error: Invalid contact object directive ‘TO’.
Error: Could not add object property in file ‘/usr/local/nagios/etc/objects/contacts.cfg’ on line 36.

 Check your configuration file(s) to ensure that they contain valid
 directives and data defintions.  If you are upgrading from a previous
 version of Nagios, you should be aware that some variables/definitions
 may have been removed or modified in this version.  Make sure to read
 the HTML documentation regarding the config files, as well as the
 'Whats New' section to find out what has changed.
