Hello delfinovc,

This message means you cannot set the category to private if it is default category (or vice versa).

Hi,

The permission off the category is viewable by all users: http://screencast.com/t/mJKTaS2AJww

The permission off the post is viewable by all users: http://screencast.com/t/VuuKWe419pqy

And the post authentication required: http://screencast.com/t/BK6ypVkG

What happens?

Hello delfinovc,

Although the post is viewable by all users, it still needs authentication if you have set the password. If you didn't set any password and it is still require an authentication, there is something wrong. You might want to provide us your backend and FTP access so we can check on this issue.
