O'key
have the k2-material and the position of the module, example "sidebar"
added code {loadposition sidebar} in material, but the module is not displayed :huh:
all needed plugins set turn on
and html-code of material is right

Hi. What do you mean when you say "material" ? Is there a link to your site?

is meant to add code
{loadposition sidebar}
to the content for loading module on chosen content page
sorry, i can not show link

Content plugins do work in the K2 module. Of course you need to place that code into the item text, not in the template.
