Zendguard, php 5.3.5?

Question

PHP

I have a Debian Squeeze system, php5.3.5 (from dotdeb), I have a site coded by Zend, the site was hosted with php 5.2.x and Zend Optimizer, now I'm trying to transfer it to a dedik with Zend Guardom installed (as I understand it replaces Zend Optimizer). But the site does not start, it does not write anything to error.log, it gives out " 500 Internal Server Error ". What could be the problem?
in phpinfo() shows that Zend Guard is enabled.

This program makes use of the Zend Scripting Language Engine:<br/>
Zend Engine v2.3.0, Copyright © 1998-2010 Zend Technologies<br/>
 with Zend Guard Loader v3.3, Copyright © 1998-2010, by Zend Technologies<br/>
 with Suhosin v0.9.32.1, Copyright © 2007-2010, by SektionEins GmbH<br/>
...<br/>
Zend Guard Loader:<br/>
Zend Guard Loader enabled<br/>
License Path no value<br/>
Obfuscation level 3 <br/>

In php.ini I wrote like this:

zend_extension = /full/path/to/ZendGuardLoader.so<br/>
; Enables loading encoded scripts. The default value is On<br/>
zend_loader.enable=1

Answer 1

The script (website) must be coded for the new Zend Guard, and therefore does not work.

Answer 2

But in general, I would look at the logs for a start. The 500th error can mean a lot of things.

Answer 3

Can I guess? Script - Reg.Panel?:)
If yes - released version under 5.3. Almost a year of waiting.

Answer 4

Mda does not work on 5.3
tried as described in the article
www.globatel.ru/blog/byuzand/28.php
also does not plow

Answer 5

At the moment, zend optimazer+ has been released supporting php 5.3. But the trouble is that it does not support 5.2. Need to encode data with new zend
