Thanks for the follow-up. I think I posted originally because i saw that the RC “Post revisions” metabox does not appear on the admin page for documents, as it does for other post types. Instead there is a “Revision log” metabox, which I assume comes from the WP Document Revisions plugin; that one shows the revisions but offers no way to delete them manually. I see now that I can set automatic deletion through the RC settings page, and since you say that works, it’s better than nothing.
I had disabled the RC plugin because it was also giving me warnings about static and non-static callbacks, but I’ve been able to fix that in other plugins. I’ll give it another try.
