Run a symfony project on hostgator

I have been trying to run a symfony project I created recently using symfony 1.4.

But pointing to the url (xyz.in) simply shows up the directory structure of the application

In the CPanel I have edited the document root to be upto app/web/ directory

After doing this all I can see is a blank page and nothing else.

What might be wrong? What are the necessary steps for deploying a symfony project to a shared hosting?

You can check the rights on cache and log directories, Apache needs write rights. Ther are many problems with symfony and shared hosting, but it's not an impossible task.
