no showing posts in /category view

Hi,

My site: https://windows7design.com/

I lost good top meny navigation.

I use those two plugins:

Redirection -> with setup: source: /category redirect (301) to target: /
WP No Category Base

Even when i disable both of them and go with category name link:
https://windows7design.com/category/windows7-gadgets

It is not showing proper posts from this category.

Please advice.
