I suspect you have incorrect permissions on one of the scripts, and you are testing as root. 

try the following: 
su - <nagios user> 
cd /usr/local/nagios/libexec 
./check_nrpe ... 

Sometimes the errors returned to the Nagios web interface can be masked by underlying issues. Ensure the scripts and executables have rx permissions for the nagios user.
