[CMS] All my attachments are gone after 4.0.3 upgrade

[Volvoholic]

After upgrading to 4.0.3, attachments for all my articles in the CMS have disappeared.

Images are now replaced by "Attachment xxx". Clicking on them says invalid attachment specified. If you have followed an invalid link contact the administrator"

If I try and manage attachments or insert an image, all I get is the lightbox loading but nothing happens. I can't re-attach my images and attachments.

Am I missing something during the FTP upload or is there something more sinister?

What did you upgrade from? 4.0.2? Were attachments stored in the db or file system?

Grant "can Download" permission in admincp > vBulletin CMS > permissions.

Hi Punchbowl: I upgraded from 4.0.2. Attachments were uploaded from computer via the image manager.

Hello Edwin: The "Can download" permission is checked.

Having this issue as well. Tried that PHP fix they released, no help. Tried this Can Download permission. No help either.
