Code Igniter returning blank page when uploaded to a server

Question

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 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.

Answer 1

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

Answer 2

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.
