hi Libincia, what version of Django are you using?

Also, what is the url that was entered to trigger this error? i.e http://127.0.0.1:8000/rango/category/broken/ ??

my django version is : 1.9.10 and i've already followed your django's version and when i added the rango_template_tags.py and rango/cats.html and added the template tags at the head of base.html , e.x

{% block sidebar_block %} {% get_category_list %} {% endblock %}

when i entered http://127.0.0.1:8000/rango/about ==> it occured the error Reverse for 'show_category' with arguments/..

Ok, so it is not the version (as Django 2 changed the package to import for reverse).

Do you have a link to your git repository?
