site.com/index.php/category_2/item/ ...

Hi. Which version of K2 are you using? Make sure that you clean the Joomla! cache. Also try to create a different menu link on a single category ( select category_2 only ) .

K2 Content v.2.6.6
Joomla! cache clean.

When leave "category_2" only,
site.com/index.php/items/item/ ...

When return "category_1" again :pinch:
site.com/index.php/category_2/item/ ..

Create a new item in system menu does not solve the problem.

system menu type - K2 content categories

Try to update K2 to 2.6.8 or use the development version from getk2.org/assets/get . Backup your site first.

maybe there will be ideas in which file K2 Content or Joomla 2.5 to look for this error?

Have you updated as i told you?

Actual.
whether there are other options to resolve this error?

this topic do not move up in the list on this forum? :huh:

What do you mean? Topics are listed by the most recent response. Regarding your problem:

1. Check all the K2 menus you have created.
2. You should have one menu link for every single category in K2.

This way your URLs should be working fine.
