Hi,
How to unlink the author name in k2 items?

Best regards!

I solved this issue in components/com_k2/templates/default/item.php by replacing author->link by author->name :)

This will lead to 404 errors but you are really cloe.
Simply remove the <a tags> altogether.

Remember to use overrides so you won't lose your edits when you update getk2.org/documentation/tutorials/174-templating-with-k2-and-the-concepts-of-sub-templates
