PHP Code Not Interpreted

PHP 5.2.1 installed on WHM 10.8.0 cPanel 10.9.0-C9565

If I load a php file on browser, it gets loaded, but in HTML source I can see php code.

If I run in SSH "php info.php", the php code gets runn and normal output is generated.

I checked these lines in httpd.conf:
LoadModule php5_module libexec/libphp5.so
AddModule mod_php5.c
AddHandler application/x-httpd-php .php .php4 .php3
AddType application/x-httpd-php .php
AddType application/x-httpd-php .php4
AddType application/x-httpd-php .php3
AddType application/x-httpd-php-source .phps
AddType application/x-httpd-php .phtml

"php -v" returns:
PHP 5.2.1 (cli) (built: Apr 9 2007 10:38:29)

On php.ini I have:
; Enable the PHP scripting language engine under Apache.
engine = "On" ;engine

I use long tags ("<?php").

I recompiled Apache and PHP few times, both from WHM and from SSH. I reinstalled Zend optimizer.
