Ajax Framework (CJAX) for Codeigniter 2.x+

Assuming you are using the latest version 5.0, Could you debug with firebug?, use the console "all" to see possible response errors and also the "Net" tab to see possible loading errors.

Additionally, you might want to turn errors on php, so if it happens to be a php error, then you'll be able to see it.

Since this is an older thread be sure to reply on the newer thread for 5.0: http://ellislab.com/forums/viewthread/220312/

Also,

Is important to note that Zend has officially dumped Windows 2003 and XP, future versions of php won't work on these platforms.
