Hi every body
I have a problem on a last release of joomla! with the last release of K2.
I trying to create a menu like this:
Category (must show a page with category title, descriprion & Sub Category block) (no items in this category)
-SubCategory (must show a page with Subcategory title, descriprion & Sub Sub Category block) (no items in this category)
--SubSubCategory (must show a page with Sub Subcategory title, descriprion & Item Listings)

For all these categories I set the catalogue mode ON and of course I choose to show Category title, description and sub category block.

But when click on the menu item of Category the Category title, description and Sub category block does not appears.
When I click on the sub sub category menu item, only the Item listing appears.

Please I really don't know which may be the problem!
I hope some one can help me!.

Ps. I using T3 Blank template with T3 Framework

Pps.
I fount in the admin panel something strange looking at the url created by joomla on these link.

this is the link of a correct working item menu:
index.php?option=com_k2&view=itemlist&layout=category&task=category&id=2

While this other is the link of the not working Item Menu:
index.php?option=com_k2&view=itemlist&layout=category

you can see this also in the two attached screenshot

Thanks in advance Fabrzio

index.php?option=com_k2&view=itemlist&layout=category is a generic non-sef URL towards all categories.
It means that you have not assigned an actual category to that menu item.

Now, as for the two menus, you need to double check the categories' settings. If they are inheriting their settings from another category you need to edit the 'master' category's settings.
