Some files have been deleted from the my server.
When I go to a node with a missing file, I have a "?" instead.
If I try to reUpload this file, the upload seems to work, I save the node and… always the "?" and on the directory no files uploaded…
However if I edit the node, remove the missing file, save the node, reEdit, upload and save, no problem !
It is a known bug or I miss something ?
