Codeigniter Website Showing Blank Page in AWS Elastic Beanstalk

base_url should not include myAppFolder it should just be your domain name with a trailing /. If your index.php is not in a folder in the bundle you are pushing, go to you EB config -> software configuration and set the following;

document root: /
environment properties: key CI_ENV value production

On the server this is where your files are:

/var/app/current/index.php
/var/app/current/.htaccess
/var/app/current/myAppFolder
/var/app/current/myAppFolder/system
...

Apache serves /var/app/current + your document root set in the control panel.

Okay so I've set it back to http://xxxxxxx-xxx.xxxxxxxxxx.xx-xxxx-x....xxxxxxxxx/
in the config file. I've also set the doc root and env properties.

It's still returning a blank page.
