Hi there!

I need your help: I got an user page where no items written by this user are displayed. Settings of items count on user page can be changed (you can see it with pagination) but there no headings, text or images of user items on user page.

Settings in K2 - Parameters - Layout and Views - Layout & view options for user (author) pages seems to be fine.

Here's link: kammerfrau.ru/blog/itemlist/user/62-testerkatya

Same issue with article calendar: nothing displayed and items count can be changed (can see pagination).
Example of issue with calendar here: kammerfrau.ru/blog/itemlist/date/2014/4/4

Guys, help me please!

Hi. This looks like a template issue. You can see that the default template works kammerfrau.ru/blog/itemlist/user/62-testerkatya?template=system. So you need to ask your template provider for help on this.
