THANK YOU! This should be on top of the K2 forum! Or "Andrey Miasoedov" should get a price from K2 for openly publishing a suggestion on how to fix this issue.
The ONE (of a couple of) place(s) (on a site with more than one publisher) where it is imperative that you can display the author it isn't possible by default?!
Don't get me wrong, I love K2 and everything about it (almost, apparently hehe), but this feels more like an oversight
Anyway, thank you again for this working solution.
To any K2 dev team member reading this... Please consider adding the option of displaying the author on ANY and ALL possible pages where author and content go hand in hand and thank you as well for a superior CMS add on (that should be a part of Joomla core )
