Extension Problem

Hello folks,

I’m having problems with two extensions that work together called Yiifilemanager and Yiifilemanagerpicker. I installed it accordingly and followed all the instructions on how to use it. The jQuery part seems to work smooth but whenever I upload something I get server internal error 500 and it does not show anything. It uses AJAX and I’m not sure if AJAX is receiving any file. I only used the demo code that can be found here. http://www.yiiframework.com/extension/yiifilemanagerfilepicker/
