I would appreciate some help on this as well. I am enjoying K2 and I would love to find a way to make the 'module K2 tool' work when set to Calendar with Subcategories.
I read the old thread but the code in the 2.5.4 version is different and I fail to grasp all of the php code in it :)
On a side note: I am running a Joomla! site in Polish, and when the calendar displays the date it is in English, but when I select >>next month, it switches into Polish! That seems like a bug, right?
Congrats to the team. Evge patriotes :)
