fix(function): error with newer Hugo versions

[nekr0z]

fixes #518

Code looked good.
I guess we need to create a fork and maintain this, but must be the most public as possible.
My two cents might be the constant feature request from users and the maintainer backed away.

@dillonzq Can you add maintainers?

This change I moved to the new fork 😄

Since the developer has unfortunately abandoned the project 😞, I would like to take responsibility for its support and development in the future.

I focused on adding new features, refreshed the design of the posts, fixed the bugs I found.
There were so many changes (the ability to choose a separate design for the post, breadcrumbs, a new comment system and much more), and so much to do, that I decided to give the template a new name uBlogger.

Short and basic, what I have changed

I will be glad if you look at it, you may like the updated design.

I'm taking a look into the new theme.
