Hi @thisisfuckingalex

First, welcome to the forum. Please consider changing your username to something more polite in line with the code of conduct.

For your template tag - did you read the guide? Do you have an file? Can you import the module in the shell fine?

>>> from blog.templatetags import blog_tags
>>> blog_tags.total_categories()

Is blogs in INSTALLED_APPS ?
