Under the administration tab the Show menu entry creates the following link on the inbox/outbox page

This is not good as I do not allow direct access to the component and the link to my forum is

I have tried all the various options Kunena, Kunena 1.6+, Kunena 2.0+, Kunena 3.0+ and they seem to give the same link.

Can this be changed to a manually configured link?

Also Use profile links and Show thumbnails are likely affected.

Thanks
