I am trying to access my PHP file in /var/www/htdocs via http://localhost/index.php

Apache HTTPD runs as 'apache:apache'. Has UID/GID above 100. The file/folder permission are 600/700. There is no suPHP error log created. Apache access log shows the access entires with successful return codes. There are no errors in Apache log files.

The scripts that work with mod_php doesn't work with mod_suphp. With mod_suphp, the PHP code is webpage is shown as it is.
