Upgraded To PHP 5 And Simple Includes Are Not Working

We upgraded 7 servers from our network from PHP 4.4.7 to PHP 5.2.5, and Apache 1.3.3.9 to Apache 2.0.61. In only one of this servers we found problems with includes...

Include example that works:

Code:
<?
include("http://www.google.com");
?>
This doesnt work:

Code:
<?
include("path/file.php");
?>
And path/file.php does exist, also log error from apache doesnt even show a line .

allow_url_fopen was replaced by allow_url_include and it's set to On.

Im using PHP 5.2.5, Apache 2.0.61, cPanel and RHES 4.
