[clue] PHP 5.3.3 (Bang Head Here)

[Jug Knot]

Clue-List -

I work with 2 Centos 6.2 boxes side-by-side (with different
behaviours).  Both are basic LAMP servers, one is a beef-ed up server
(for KVM hosting) and the other is a 'sandbox' installed as a
'Minimal' Centos 6 configuration.   My current project is to 'kick the
tires' on Drupal 7 and WordPress and look to setting up a next-gen
site for my portal --> http://securityfeeds.com/drupal

My current 'Bang Head Here' moment comes from looking at the PHP
operation on these two boxes (php.ini, php.conf files are identical).
Here's the scorecard -

Minimal Server - PHP 5.3.3 installed, PhpMyAdmin installed and running
(for Drupal), simple functionality (php testing script) works fine

Beefy Server - PHP 5.3.3 installed, WordPress (all *.php scripts)
running fine.  All browser calls to PHP scripts yield either 'white
screen of death', or 'File Not Found'
      errors.  Cannot bring up PhpMyAdmin (file note found)   <-- Go figure

I've spent a 'wheels spinning' Monday trying every Debug tip I could
find.  Neither box wants to write to the /var/log/php_error.log that
gets configured into the
'php.ini' script.   I'm also hesitant to uninstall/reinstall the PHP
module while I have a WordPress instance configured and working.

Thanks for any advice.
