Installed Zend Guard Loader not working.

http://wawa.net.au/test.php

Pls check above link for php configurations

I added the following code into my php.ini file:

[Zend.loader]
zend_extension=/usr/local/zend/ZendGuardLoader.so

The .so file is also in that position

I've even rebooted my vps.

The zend guard loader just doesn't work.

Pls help, thanks
