Following a WordPress upgrade you may find uploads stop working. The exact cause of this problem remains unknown, but some users report fixing the problem by simply resaving their upload settings.
If you experience this problem, please try the following.
- Navigate to Admin > Settings > Misc
- Click the Save Changes button at the bottom.
- Attempt to upload a file as normal.
NOTE: If a media item fails to upload, broken uploads will not be fixed by following the above procedure, a new media item should be uploaded to verify if the fix was successful.
