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.
