Zend installed - VBSEO does not see it

I have a brandnew server and installed Zend Optimizer on it. However, when I move one of my forums running VBSEO to the server, instead of seeing the forum I see a page telling me that Zend is not installed.

Zend Optimizer not installed
This file was encoded by the Zend Encoder / Zend SafeGuard Suite
In order to run it, please install the freely available Zend Optimizer, version 2.1.0 or later.

I verified that Zend Optimizer is installed via (root/SSH) "php -v" and get the following output:

[root@hostname ~]# php -v
PHP 4.4.7 (cli) (built: Jul 16 2007 11:26:04)
Copyright (c) 1997-2007 The PHP Group
Zend Engine v1.3.0, Copyright (c) 1998-2004 Zend Technologies
with Zend Extension Manager v1.2.0, Copyright (c) 2003-2006, by Zend Technologies
with Zend Optimizer v3.3.0, Copyright (c) 1998-2007, by Zend Technologies

Any idea what is going on and why VBSEO does not see it?

Thanks.

Hello,

in some cases test script cannot detect Zend Optimizer correctly. Feelf ree to install Zend version of vBSEO since you have zend optimizer signature in phpinfo().

instead of seeing the forum I see a page telling me that Zend is not installed.

Please make sure that you have the same configuration for Apache's PHP module (not only for command line php). You might try to restart Apache and see if that helps.
