I rechecked this for manage deleted posts. It uses the same var $show['harddelete'] on posting.php. So it should work the same way, without extra code modification.

Do you have a test user with mod rights or did you checked the manage deleted post site as admin? As admin it should work anyway.

I checked logged in as a supermoderator. the option for "physically delete" was not available in "manage post" yet it was available in "Manage Thread"

if anyone can post what I would have to do to get that fixed I would be eternally greatful.

usefull thanks
