As Admin I have edited a post in which there was an attachment which is not allowed by our forum rules.
I removed the link to the attachment but the link remains in the edit history, and the attachment also remains (it can still be downloaded).
Can I completely remove/delete the attachment? (it’s a PDF file)
Search your admin settings for clean and you should get some options for handing orphaned uploads (though I don’t know if this is technically considered orphaned).
In the revision history, you should be able to hide a revision. I’m not sure those revisions are even viewable by non-moderators if it isn’t a wiki post.
Uploads (images/attachments) that are only referenced in a revision are indeed considered orphans.
By default revisions are visible to all users. You can disable this in site settings.
That won’t matter, though, because as @zogstrip pointed out, uploads referenced in old revisions get culled and deleted eventually.
Turning off all old revision viewing in this case would be a “boil the sea” solution and definitely not recommended.
To be clear, not suggesting that hiding revision history is the solution here - just clarifying Wes’s post.
