Zend is installed... no it isn't.. yes it is

Just moved to a dedicated server running php5 and Zend.

The test file says Zend isn't installed but phpinfo returns:

This program makes use of the Zend Scripting Language Engine:
Zend Engine v2.1.0, Copyright (c) 1998-2006 Zend Technologies
with Zend Extension Manager v1.2.0, Copyright (c) 2003-2007, by Zend Technologies
with Zend Optimizer v3.2.8, Copyright (c) 1998-2007, by Zend Technologies

Anybody know what might be causing the confusion?

Hello,

sometimes (like in your case) test script is unable to detect Zend Optimizer correctly. Your phpinfo clearly shows that it's ok to use Zend version of vBSEO for you.
