PHP connector not working

Hi there,
First of all, let me thank you all for the great work.
Although, I ran into a problem when connecting using php. Basically, I can see the image browser but no folder is created and no file is uploaded.
I've installed the editor under /fck/ and it contains the php connector.
Here are the changes I made:

/fck/fckconfig.js

FCKConfig.LinkBrowserURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Connector=connectors/php/connector.php" ;
FCKConfig.LinkUploadURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Connector=connectors/php/connector.php" ;

FCKConfig.ImageBrowserURL = FCKConfig.BasePath + "filemanager/browser/default/browser.html?Type=Image&Connector=connectors/php/connector.php" ;


/fck/editor/filemanager/browser/default/connectors/php/connector.php

$GLOBALS["UserFilesPath"] = '/fck/UserFiles/' ;


I have created the folder and set the proper right.
I did not get any errors back which is kind of frustrating.
Can you please help me?
Cheers,
Paul
