Error 503 in OpenShift server

Question

That's my first Django project and I'm trying to deploy it to OpenShift, but I have a problem: when I'm trying to open app's page, I see "503: Service Temporarily Unavailable" message. I thought that app wasn't started so I tried to launch 'ctl_app start' in ssh and I've got this:

python: can't open file 'app.py': [Errno 2] No such file or directory

I tried to start app this way: rhc app start customerquiz and got this:

RESULT:
customerquiz started

But it took no effect. Well, I tried to look the state of app:

$ rhc app show --state customerquiz
Cartridge python-2.7, mysql-5.1, phpmyadmin-3.4 is started

And that's what in server logs:

$ rhc tail customerquiz

Does anyone have any ideas what can be wrong?

P.S. That's deployed project source code, if you need it: https://github.com/uncleLem/CustomerQuiz (I just changed database connection parameters).

P.P.S. Oh, BTW, if I open https://customerquiz-unclelem.rhcloud.com/phpmyadmin/ directly, I can see phpMyAdmin page.

We are not using mod_wsgi with these new carts. 2.7 uses gevent and 3.3 uses WebOb

Take a look at how we set up the app.py in the 2.7 cart
https://github.com/openshift/openshift-community-cartridge-python-2.7/blob/master/template/app.py

and for 3.3
https://github.com/openshift/openshift-community-cartridge-python-3.3/blob/master/template/app.py

Can you review the following blog post to see if it helps?
