We're having trouble getting Dropbox to work. We have Omeka installed in a WebDAV environment, and after copying the files to the "files" directory, attempting to upload a file from Dropbox generates the following error:
"The file '4A-05-01.jpg' is missing and could not be ingested., The file '4A-05-01.jpg' could not be ingested because it is not readable."
The correct permissions are set for the appropriate directory. We have no trouble with uploading any other files through the "Add Item" interface, and all are standard .jpg files.
