Hi there!
I'm having some trouble with menu items. I've created a menu and added to it all the categories of my site: I've created an item for each category and configured each menu item as a K2 "Latest items from one or more (user) or categories. In the menu item options page, I've selected the category from wich I want the articles to be displayed and configured the rest as desired.
When I click the menu item in the menu, I'm being redirected to that category but no articles are showed. I know for sure there are articles assined to that category because they are also showed in the main page, but they do not appear in the category page.
What can I be doing wrong?

Does the articles appear if you set the menu item to just K2 Categories instead of "Latest items from one or more (user) or categories"

Yes! They now appear !
Why would that be?

Thanks!

I think you mis-configued the "Latest items from one or more (user) or categories" menu item, if you're going to just display all the items in a category just use the K2 Category menu item
