ZendOptimizer & SourceGuradian problem with Plesk 10.4.4 Freshinstall

[RasaNegar]

Plesk Panel for Linux, 10.4.4, CentOS6X, X86_64

we rent a server and install a fresh plesk installation on it ( with PHP 5.3 )
after that migrate the other server (also Plesk 10.4.4 - update 13 - PHP 5.2.17) domains

but there are some sites that have problem with sites must be decoded with Source-guardian and ZendOptimizer ( 3.3.0 on old Server )

as you know we have to use Zend Guard Loader on PHP5.3 but the script is not compatible and Source guardian scripts have the same problem

we try to Downgrade to PHP 5.2.17 but its not load zend-optimizer
but its load ioncube!

here is the php -i | grep zend

Loaded Configuration File => /usr/local/Zend/etc/php.ini
Zend Extension => 220060519
Zend Memory Manager => enabled

and here is the PHP -v

with Zend Optimizer v3.3.9, Copyright (c) 1998-2009, by Zend Technologies

but in phpinfo on domian we see

and lots of problen in cms like joomla
openbasedir and zip enable

we tried everything ....
after lots of Goggling and change we
