@msaelices Do you know what version of Django this is happening on specifically?

This error leads me to believe you have and issue with not defining silk URL's with it's own namespace. See:
https://github.com/django-silk/silk/blame/master/README.md#L62

[msaelices]

I'm using Django 1.8.5 and I correctly added the URL with the silky namespace.

I've spent hours debugging an issue, only to find the url configuration for silk is required. This PR prevents my entire site from crashing due to silk not having the URLs configured, so 👍
