zend Optimizer vs. Ion Cube and test.php

I installed Zend Optimizer yesterday in preparation for vBSEO. I uploaded the test.php from the vBSEO zip file just to make sure everything was installed correctly.

test.php is telling me that Zend is not installed but Ion Cube is installed and it tells me to use the Ion Cube version of vBSEO.

Never installed Ion Cube on this server.

PHP 5.16
ZendOptimizer 3.2.0

PHP Info shows Zend Optimizer is installed.

"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 v1.0.11, Copyright (c) 2003-2006, by Zend Technologies
with Zend Optimizer v3.2.0, Copyright (c) 1998-2006, by Zend Technologies"

any ideas as what I should do next?

Should I just install the Zend version of vBSEO and cross my fingers?

Hello,

sometimes test script is unable to detect Zend Optimizer correctly. In your case, you can proceed with installation of zend version of vBSEO.
