Problem with test.php

Okay well I am considering purchasing vbSEO because one of the admins that runs one of our affiliate forums has just prchased it and says it's been great for helping with google PR and getting pages listed. Now I am always for anything that might increase the number of people visiting our board so I decided to look into this.

The board in question is actually somewhat large (over a million posts, etc.), now it is not huge but still pretty big. I have read a few threads here daling with that and it seems that this is not a real problem and the load increase can be worked on to minimize it.

Now here is my "problem" I decided to run test.php you guys provide to check for configuration and I get a really wierd result. First of all I get a check besiders Zend Optimizer(as expected, I installed zend 3.0 myself a few weeks ago), but then at the bottom I get this message:

"This test script was unable to find Zend Optimizer on your server and was unable to successfully run Ioncube. "

So I am wondering what the hell is up with that, what is happening, zend was installed in the default place etc. Will I even be able to run vbSEO, and if I won't be able to run it what is the point of shelling out $150 on it. I hope it will work but I am sort of confused as to why I am getting this message and what exactly it wants me to do.

If you guys need to see test.php tell me and I will be happy to PM it but I don't quite want to post it here out in the open.

Hello,

the test script sometimes fails to recognize the encoding libraries installed.
Please PM the URL to your test.php.
