I want to show the category of each post in the content-single.php (without the folder icon) and not in the content.php (home, category archives, etc).
I tried that but with that fix the category is showed in every post (without css) in content.php and content-single.php and I only want that in content-single.php, not in home, category sections, etc.
With that code is solved, but the category is showed without any css. I don’t want the folder icon, but I still want the same old css for the category word so I think that you have to tweak the code again.
