Erreur sur le fichier resource.cfg

Bonjour,

Bonjour,
après installation et configuration de nagios j'ai vérifié les fichiers de configuration a l'aide de : sudo nagios3 -v /etc/nagios3/nagios.cfg
le message suivant s'affiche :
error: Unexpected token or statement in file '/etc/nagios3/conf.d/resource.cfg 'on line 24

voici le fichier resource.cfg en question:

###########################################################################
#
# RESOURCE.CFG - Resource File for Nagios
#
# You can define $USERx$ macros in this file, which can in turn be used
# in command definitions in your host config file(s). $USERx$ macros are
# useful for storing sensitive information such as usernames, passwords,
# etc. They are also handy for specifying the path to plugins and
# event handlers - if you decide to move the plugins or event handlers to
# a different directory in the future, you can just update one or two
# $USERx$ macros, instead of modifying a lot of command definitions.
#
# The CGIs will not attempt to read the contents of resource files, so
# you can set restrictive permissions (600 or 660) on them.
#
# Nagios supports up to 32 $USERx$ macros ($USER1$ through $USER32$)
#
# Resource files may also be used to store configuration directives for
# external data sources like MySQL...
