Thanks for the answer. Tryed to experiment with this a little bit. But nothing changed. Maybe thats because i'm working on it on xampp at the moment in my localhost. Of course with cache and cookies deleted, also CTRL F5 for refresh used.
But tryet to change categories ant sub categories to template - blog. Nothing changed. Still in main page with cursor on images can see items name and category showing.
Tryed to change one of the default template categories from blog to portfolio template. it startet showing me name instead of +, but trying to change it back, didn't work.
I will try to experiment more, and maybe upload the site on internet to see how it works online. Maybe something will change.
