for my new project I decided to use [django-userena](https://django-userena.org/)

I followed the instructions from [userena docs](http://docs.django-userena.org/en/latest/installation.html). However I'm getting this error :

> 
> SiteProfileNotAvailable at /accounts/signin/
> 
> 
> No exception supplied
> 
> 
> 

and don't know how to fix it. Please help !
