Looking for a blogging lightweight CMS : selfhosted

I’m looking for a lightweight CMS that I can use for blogging. I know WordPress is great and always recommended but in my opinion it’s too bloated, takes time to maintain it and multiple vulnerabilities are pain to deal with.

I’m just looking for a simple CMS that is basic, fast and doesn’t require a lot of maintainance as I don’t have hours upon hours of testing the latest versions and plugins. I rather need something that I can setup and forget type of CMS.

The features I look for are:

CMS can be hosted on Shared Hosting
No Databases
Viewing the front end of the blog is compatible with mobile devices like smartphones or tablets
Has a lot of templates either free or paid
No comments section but it would be a plus if there was some type of 3rd party integration of it, e.g disqus.
Ease of use
