Slideshow CK

[ Moderator note: moved to Fixing WordPress. ]

Hi everyone!
I have installed the plugin Slideshow CK. I have uploaded photos on it. When I copy the shortcode to a post, to test it, nothing shows up (not even the shortcode). I am kind of new to WordPress, but I really don’t understand the reason why this happens. I have the version 1.0.22 of the Plugin, and the version 4.7.2 of WordPress, that I use on Google Chrome. Here is a link to a post that I have made to test it.
Any help would be really appreciated!
Thanks!
