</code></pre>

<p>I add my configuration to settings.py. It will load my configuration from /etc/cloudmjpeg/cloudmjpeg.conf. </p>

<pre><code>from cloudmjpeg.utils import configloader
MJPEG_CONF = configloader.get_configuration()
</code></pre>

<p>Howerver I remove load my configruration into settings.py. It will run app using python manage.py command line perfect. So that I think when I load my configuration in settings.py, it will be error. Why?. I do not any idea to resolve problem. Please help me.
Thanks</p>
