It's so strange, because in another template it works without errors.

Can you help me? Thanks.

From the django-avatar docs:

{% render_avatar avatar [size in pixels] %}

Given an actual avatar.models.Avatar object instance, renders an HTML img tag to represent that avatar at the requested size.

So, in your view, you need to get the avatar associated with the user: avatar = Avatar.objects.get(user=request.user)

Then pass that variable into the template.
