Problem solved

I dig throu error.log after my administrator enable it for me
Here is the instruction i give him to enable them for me

These instructions to enable Internal Server Error Logging are for Ubuntu 12.10 with PHP 5.3.10 and Apache/2.2.22.

Make sure PHP logging is turned on:

Locate your php.ini file:

el@apollo:~$ locate php.ini
/etc/php5/apache2/php.ini

Edit that file as root:

sudo vi /etc/php5/apache2/php.ini

Find this line in php.ini:

display_errors = Off

Change the above line to this:

display_errors = On

Lower down in the file you'll see this:

;display_startup_errors
;   Default Value: Off
;   Development Value: On
;   Production Value: Off

;error_reporting
;   Default Value: E_ALL & ~E_NOTICE
;   Development Value: E_ALL | E_STRICT
;   Production Value: E_ALL & ~E_DEPRECATED

The semicolons are comments, that means the lines don't take effect. Change those lines so they look like this:

display_startup_errors = On
;   Default Value: Off
;   Development Value: On
;   Production Value: Off

error_reporting = E_ALL
;   Default Value: E_ALL & ~E_NOTICE
;   Development Value: E_ALL | E_STRICT
;   Production Value: E_ALL & ~E_DEPRECATED

What this communicates to PHP is that we want to log all these errors. Warning, there will be a large performance hit, so you don't want this enabled on production because logging takes work and work takes time, time costs money.

Restarting PHP and Apache should apply the change.

Do what you did to cause the 500 Internal Server error again, and check the log:

vi /var/log/apache2/error.log

You should see the 500 error at the end, something like this:

[Wed Dec 11 01:00:40 2013] [error] [client 192.168.11.11] PHP Fatal error:  
Call to undefined function Foobar\\byob\\penguin\\alert() in /yourproject/
your_src/symfony/Controller/FuckedUpController.php on line 249, referer: 
https://nuclearreactor.com/abouttoblowup

The problem was with "Fatal error: Access to undeclared static property: Smarty::$_CHARSET"

Solution:

I edit /core/model/smarty/Smarty.class.php

after

const PLUGIN_COMPILER = 'compiler';
const PLUGIN_MODIFIER = 'modifier';

i add

/**#@-*/
 
/**
* assigned global tpl vars
*/
 
/**
* error handler returned by set_error_hanlder() in Smarty::muteExpectedErrors()
*/
public static $_previous_error_handler = null;
/**
* contains directories outside of SMARTY_DIR that are to be muted by muteExpectedErrors()
*/
public static $_muted_directories = array();
/**
* Flag denoting if Multibyte String functions are available
*/
public static $_MBSTRING = SMARTY_MBSTRING;
/**
* The character set to adhere to (e.g. "UTF-8")
*/
public static $_CHARSET = SMARTY_RESOURCE_CHAR_SET;
/**
* The date format to be used internally
* (accepts date() and strftime())
*/
public static $_DATE_FORMAT = SMARTY_RESOURCE_DATE_FORMAT;
/**
* Flag denoting if PCRE should run in UTF-8 mode
*/
public static $_UTF8_MODIFIER = 'u';
