the breadcrumb block came with Astra Pro Theme. I’ve contacted with their support team and they told me that “it is the default functionality of WordPress”.
I’m using a demo server, in order to test things first and then apply them to my productive server. So, you could navigate to http://195.251.99.141/wordpress/post-3/ and press “Main category” from the breadcrumb. Post 1 and 2 belongs directly to “Main Category”, but post 3 and 4 belongs to subcategories. Those posts shouldn’t be displayed.
As you can see in the left side of the picture below, I’ve set the Font and saved the settings. When I come back to Style Editor, everything is set to defaults (right side).
Thank you for your immediate reply. You were right, it is a plugin that messes everything up. I deactivated it and everything is working perfectly. Thanks a lot.
