 Admin role no longer letting her upload her WOFFs.

 Hi @eddiemcham. Following up, this is definitely a MIME issue. As others
 have indicated, the problem is the way WordPress is verifying that the
 uploaded file really is what it claims to be. If the specific server isn't
 able to verify that the file is a WOFF file, it will respond with
 `application/octet-stream` (a common default when the filetype is unknown
 to your server). Users without super-admin privileges are not able to
 upload  `application/octet-stream` files on multi-site, which is why this
 is failing for your colleague.

 There are several related cases of this sort of thing happening in
 different configurations so combining this conversation in #40175 will
 help us address all cases.
