Question Panic - users getting moderator messages and access controls not working

I can't find a category "Problems with Kunena 3", so I'm hoping I'll get read here.

I've had to shut down our Kunena forums because all of sudden lots of users are receiving messages telling them that they are moderators. Another thing that suddenly started happening is that ex members of a group are receiving these messages and can access categories belonging to the group that they used to be members of. These are private forums and very sensitive, so the group is all of a panic thinking that all and sundry can read sensitive information. I am really stressed out and I'm receiving 10 emails per minute with complaints. Can anybody help PLEASE? Config below:

Update: Kunena says all these users are site admins, but they're not! They're just ordinary users. Obviously that's why they're all receiving the messages and have super powers in the forums. Do I have to hack the DB?

Update:

It seems that all users with "editor" privs are considered site admins by Kunena. Is this a bug in Kunena?

K3.0.6 isn't supported anymore. Please update.

check the permissions on the kunena dashboard -> options top right

Oh. I always install updates when they appear, but the Joomla update manager hasn't mentioned an update for Kunena.

Yup. Only Admin and SU can do anything.

Oh, and in config, I have "Enable version check" set to Yes.
