I set up a test website with a fresh install (NO quickstart package) of Joomla 3.5.1 + Couda template + JF Slideshow + K2.
Even though I set JF Slideshow module to show only on the home page, it also appears in every K2 single article view.
How is that?
Please check the issue HERE

You need to create a new menu item for K2 category view.

Thanks for your reply but that's not the point.
Please check this single K2 item.
As you can see, JF Slideshow is present even though it is set to be shown only on the home page.

Can you please send me the super admin access via private message system?

Hi.
Sent you the access a week ago.
Found anything?

I'm so sorry.
I've changed code (if you create hidden menu item for Recensioni category, code doesn't need to change), so JF slideshow module doesn't appear in every K2 single article view.
