ioncube issues

[kkonline]

I have a script encoded with ioncube
but on my script it shows

Site error: the file /var/www/web1/classes/setupclass.php requires the ionCube PHP Loader ioncube_loader_lin_5.2.so to be installed by the site administrator.

although in php.ini i have mentioned
zend_extension=/usr/local/lib/ioncube/ioncube_loader_lin_5.2.so
in the first line

in the php.ini other refernce to szend is
; Enable compatibility mode with Zend Engine 1 (PHP 4.x)
zend.ze1_compatibility_mode = Off


echo phpinfo() mentions

Variables
_SERVER["argc"] 0
_ENV["PATH"] /usr/local/bin:/usr/bin:/bin
_ENV["PWD"] /usr/local/lib/ioncube

Environment
Variable Value
PATH /usr/local/bin:/usr/bin:/bin
PWD /usr/local/lib/ioncube
LANG C

What can be done in order to run the encoded script

Do you use the correct php.ini?
Does /usr/local/lib/ioncube/ioncube_loader_lin_5.2.so exist?

[kkonline]

yes the .so file exists in that path and i have verified the php.ini using the phpinfo() function

What's the output of ls -la /usr/local/lib/ioncube/?

Do you use a 32 or 64bit OS, and is the IonCube loader for 32/64bit?
