This is just a module. K2 doesn't interfere with that. The fact that you get no options probably means that K2 content elements are not installed in your site. This happens if you install JoomFish after K2. The only thing you need to do is install K2 again ( do not unistall it! Just install the latest version ).
Hi, unfortunately does not work. I have the same versions of the freshly installed (in the order of installation). Files with the administrator / components / com_joomfish / contentelements are in place. In articles section everything is ok. I do not know what to do.
This is a module that is coming with the JoomFish. It has specific options for components. So i guess that you need to add K2 to it's configuration. Not sure how to do it exactly but i guess that a search at the joomfish forum will give you the answer.
