    We had this issue, but had to fix it differently.

    For security purposes, we had changed our user_id to a number besides 42. Our database had two rows: one with user_id of 42 and one with another number. Both had the group_id of 8. We deleted the row of 42/8 and it works fine now.

    I’ve also found that this problem can be solved by changing who is the Author of the K2 article… or whatever article I suppose. Because the initial administrator that created the template and created the article will of course not be in your DB when you install the template. So you can solve the problem simply by changing the author of the article to the admin user you create when installing the DB.
