Hi i need to ask you something...i have a module on joomla and i need to get items from k2 content and not the default of joomla...but it doesnt has this choice...i have to change something on the php code? or i can do something else?

Hi,

For sure you need to change the php code to get K2 items instead of joomla articles

You should use the K2 Content module in order to display items from K2.
