Media Gallery and links to featured posts broken in WordPress 3.8 multisite for child sites

[OceanWind]

Just upgraded to the beautiful 3.8.

But now in multisite:

1) in the media section of edit/create POST, the media gallery has gone blank (is not finding the media files associated with the site

2) the featured images are not being found

Typically, the media calls are going to:

​http://name_of_site.com/sub_site_name/files/2013/12/name_of_file.jpg

Instead of to:

​http://name_of_site.com/sub_site_name/wp-content/uploads/2013/12/name_of_file.jpg

which seems to be the new standard.

Also, migration does not seem to have fully occurred from the old standard:

​http://name_of_site.com/blogs.dir/blog_id/files/2013/12/name_of_file.jpg

Thanks!

It may be worth posting in the ​support forums first to go over some common troubleshooting. It seems like this may be related to a transition from a much older version of WordPress.

What version did you upgrade from?

I'm going to close this out for now. @OceanWind, feel free to reopen if this remains an issue after troubleshooting in the support forums.
