Django-CMS only shows parent pages

Question

I have just installed Django-cms and it works fine, but the problem is that the system only shows child pages and for parent pages a standard 404 error comes up... Preview works fine both for parent and child pages, but when I publish both of them, a 404 error is displayed for parent page.. It is strange, I have absolutely no idea why this happens. I did everything according to the introductory tutorial. Please see the screenshot:

Edit: I tried to reinstall the CMS at the problem still exists... "cms check" command line attribute shows no errors.. :|

These are my urls:

from django.conf.urls.defaults import *
from django.conf.urls.i18n import i18n_patterns
from django.contrib import admin
from django.conf import settings
from django.conf.urls import patterns

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    (r'^admin/', include(admin.site.urls)),
    url(r'^', include('cms.urls')),
)

if settings.DEBUG:
    urlpatterns = patterns('',
    url(r'^media/(?P<path>.*)$', 'django.views.static.serve',
        {'document_root': settings.MEDIA_ROOT, 'show_indexes': True}),
    url(r'', include('django.contrib.staticfiles.urls')),
) + urlpatterns

Strange indeed. Here's a couple of things to try/explore:

1. You have USE_I18N turned on, but you're not using the LanguageCookieMiddleware (disabled), and you're not using the i18n_patterns in your urls conf. Consider setting USE_i18N = False to see if that helps.

2. I also notice that none of your pages are in the navigation. This means that you're typing in the URLs manually to see if they 404 or not. Consider putting them in the navigation, then check the URL provided by the menu templatetag to see if, perhaps, the intended URLs are different than you expected.

Let me know here what you discover.
