Question

I got a Django project, with 1 application in it.

If I have debug set to True, and I hit write in a url like /sdfsdfsf then it will give an error

Using the URLconf defined in website.urls, Django tried these URL patterns, in this order:
...
The current URL, dsd, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.

I then edit the settings.py to turn off Debug, but now I get 500 error. I look in the error config and get this;

mod_wsgi (pid=17601): Exception occurred processing WSGI script '/var/websites/xxxxx/website/django.wsgi'.

        raise ImproperlyConfigured('ImportError %s: %s' % (app, e.args[0]))
    ImproperlyConfigured: ImportError cardir: No module named cardir

cardir is the name of my app in the project. However if go to a page which is not a 404 (like / or /about) the it works fine, so it can get the cardir. I feel something else is going on.

Structure;

# ls
cardir  django.wsgi  __init__.py  __init__.pyc  manage.py  settings.py  settings.pyc  static  templates  urls.py  urls.pyc

# cd templates/ && ls
404.html  500.html  base.html  index.html

Check if there is not an error in 404.html. I had similar issue some time ago.
