It's just there to tease you with the knowledge that the staff can see deleted posts and you can't. That nothing is ever truly deleted.The button just links to an error so what is the point of it? I assume for admins it does indeed bypass it being hidden and shows it but it is completely and utterly useless the majority of users...
even if it's your own which is the odd part. it would be the one odd fringe case where it would be nice. but alas, another day.The button is exactly for what you think it is: show deleted posts by the staff.
I just looked offline and it is indeed there. It really shouldn't be there, but at least you cannot view deleted content.
It's definitely an oversight. Only the staff should be able to see the "show" button.my guess is that xenforo probably has an option to make it display the show me thing and one to make it actually show you what's in there. they're separated by user group. showing you the option may not be intentional or the staff may not care. it's not harming anything, but it's kinda pointless.
