Solution : These means the VPS server it can’t read the php file . So install php #yum install php then try it. It will work perfectly.

What is Solution for That Problem Root cause For these problem is PHP file format it is not supporting because Nagios document Root document file format is php file.To resolve these issue you need to install php file #yum install php Then try it will work perfectly.
