Deploying Codeigniter to AWS EBS

403 means "forbidden". It is usually caused by incorrect file/folder permissions on the server.

I've already tried changing both the config and the .htaccess file to allow access but the same error keeps on showing up.

each file/folder need the execute flag

No, php files do not need execution flags, apache (or other webserver software) needs to be able to read them. But this is not related to the issue of the topic starter.

I think you are uploading files to the wrong directory. Try uploading a simple test.html to thE folder and try to acces it with your browser. If you dont see it, please check your apache access logs, I believe apache shows a full path in the error log when a file is not accesible.
