Resolving semi-blank screen problem with nconf on Amazon Linux
==============================================

1. Check the apache error log, I had the following error in my error_log
/var/log/httpd/error_log

[Mon Jun 02 05:39:36.149471 2014] [:error] [pid 29946] [client *.*.*.*:59964] PHP Fatal error:  Call to undefined function mysql_query() in /usr/share/nagios/html/nconf/include/functions.php on line 1016, referer: /nagios/nconf/INSTALL.php?logout=1

2. Install MySQL database module for PHP
   do rpm -qa | grep mysql
   look for your php version (php55* something)
   yum-install php55-mysql

Note: if you get this error, try to upgrade php*-common to the lastest and then install php-mysql package.

Error: php55-common conflicts with php54-common-5.4.28-1.54.amzn1.x86_64
Error: php55-xml conflicts with php54-xml-5.4.28-1.54.amzn1.x86_64
Error: php55-cli conflicts with php54-cli-5.4.28-1.54.amzn1.x86_64
Error: php55-process conflicts with php54-process-5.4.28-1.54.amzn1.x86_64
 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
