blank page with two PHP versions

[Mise]

I have a dedicated server with Apache 2.2.24, PHP 5.29 + Mod SuPHP.
I have installed php 5.29 (main) + php 5.3 following this guide: Blog - Running PHP 5.3 along with PHP 5.2.x in cPanel servers

I'm trying to configure one user with php 5.3. However, I'm getting a blank page and I can see php code in source code page:

/home/ndomain/public_html/index.php:

<?
phpinfo();
?>

inside customer /public_html I have:
- .htaccess:

AddHandler application/x-httpd-php53 .php

- php.ini
- I keep folder /cgi-bin empty

I cannot locate the error inside apache logs:

/etc/httpd/logs/suexec.log:

problem solved. I have compiled again as FCGI following this page:

How to install PHP 5.2 FastCGI on a cPanel server alongside PHP 5.3+ ? Blog ? Dave James Miller just changing php52 by php53

however the same problem arose After endless investigations the cause was an stupid thing: the option "short_open_tag" inside php.ini was in off.


We humans should be aware of thousand of invisible and stupid things in front computers because our technology is in the Neanderthal age. And so many people are fascinated with all this clumsy engineering.... Amazing. I vote to send all our software to North Korea and to end with that regime with a headache pandemic.
