during a migration of a test-installation of Omeka between two different shared web hosters I encountered the following error which seems to be caused by the dropbox plugin.
When the Dropbox plugin ist active and the "folder" file in the Dropbox directory is NOT writable, it was not possible to add new items or edit existing ones. The deletion of items, however, was still possible. After I made the "file" folder writable, everything worked fine again.
Any idea why that is happening?
