Codeigniter Website Showing Blank Page in AWS Elastic Beanstalk

Pull the logs from the EB control panel and see what it's doing. You may want to turn on show errors in your software config in EB. Or you can SSH into the box and run this:

wget -O - localhost

Logs are in /var/log/httpd

Is that giant pile of x's your domain name, like http://www.example.com/ ?

The giant pile of x's consist of the URL generated by the environment instance in Elastic Beanstalk.

I really don't get why this is happening. I've run all tests on my localhost and it works perfectly.

I also followed AWS instructions and archived the entire project into a .ZIP file.
