My code had been working fine since long with this package in django but suddenly, it has stopped with the following message.

Reverse for 'avatar_change' not found. 'avatar_change' is not a valid view function or pattern name.

I verified, all is setup correctly. Look like the problem is in this code:

href="{% url 'avatar_change' %}"

I noticed the django-avatar code was changed 2 weeks ago to fix the references. Could that be causing it?
