We have an issue on our site whereby videos uploaded to posts on subsites are returning a 404 when attempted to be viewed, whereas for instance images attached to subsite posts display just fine. We’re on a pre-3.5 multsite install so blogs.dir is still in effect for us.
Videos uploaded to the primary site play just fine. When I substitute “wp-content/blogs.dir/2/files/…” for “[subsite-slug]/files/…” in the URL the video plays just fine. Nothing looks amiss in .htaccess. Any ideas? Thanks!
