XF 1.4 Member Overlays - hidden from guests?


Well-known member
As per title, is it possible to hide member overlays from guests?
As it stands, anyone viewing the forums, can click the member link and the overlay pop up will show the avatar, and fields.

Same said for thread 'likes' - if one clicks the link, you see the overlay containing all the users' info.
Is it possible to prevent this?

I've adjusted everything I know really in the permissions, but it's still to no effect.

I would appreciate a pointer with this, and if it is even possible.
Many thanks!
