Ajax Framework (CJAX) for Codeigniter 2.x+

[eluser]Simple Focus[/eluser]
Hi, I was hoping someone that has used this framework successfully can help me troubleshoot an issue.

I am trying to get CJAX to work and get 500 Internal Server errors with anything that uses the framework. This includes the default out-of-the-box request that the instruction page says should work http://www.domain.com/ajax.php?test/test, as well as any of the example files.

I have tried the following on both a local server and a production server to rule out local problems:

1. I downloaded the latest Codeigniter package (2.1.2) and got it successfully working.

2. I installed the framework (5.0 Stable) as directed on the instructions page (basically just copied the files to the server). I have done nothing else to the Codeigniter installation. I tried both with no .htaccess file and renaming the htaccess.txt to .htaccess.

Does anyone know what would cause the 500 errors? Was there something that I should have done to the default Codeigniter installation prior to attempting to install CJAX?

Thanks for your help.
