I set in K2 component, that comments to K2 articles can give only registered users.
When new user registers to Joomla users, this user is not automatically also in K2 users - it must be set manually.
New use can not give comments to K2 articles.
It is not good for News website with many new users.
I try set in K2 component in advance settings Allow user profile K2 to Yes.
Registration form changed to K2 registration, but this registration does not work.
Even if I fill in all mandatory fields, an error message will appear: "Empty solution is not acceptable"
Can you advise me any solution?
