Solution:
I think best way is to create a subdomain e.g. news.gditac.com, install there your wordpress and make a permanent redirect from https://gditac.com/news to https://news.gditac.com
If you really want to install it on a subfolder then read this article: https://wordpress.stackexchange.com/questions/134839/is-it-possible-to-install-wordpress-within-wordpress-installation
