Code Igniter returning blank page when uploaded to a server

I just uploaded my codeigniter directory to my unix server and I am getting a blank page. The same directory is located in my desktop web server where it works just开发者_高级运维 fine.

Also, I uploaded a fresh copy of CodeIgniter directory to my unix webserver and that just works fine.

Do any of you know what could be the problem?

Thank You.

Make sure you edited your config.php with proper settings located in /system/application/config/

Blank pages are usually caused by PHP errors. Copy and paste the code into an IDE like Aptana with live debugging and see if it throws any errors.
