Not sure if anyone can help, but the Omeka forums have so far not been helpful.
I used dreamhost’s excellent one-click install of Omeka and everything has been up and running for awhile now. My problem comes from what I think (but may be wrong) is an issue between dreamhost and a plugin on omeka called dropbox. The plugin is supposed to allow for batch uploads of files. When I was with another host, batch uploads worked fine which is why I think the issue may be with dreamhost. Even single-file uploads only work about 50% of the time.
Does anyone have any experience using Omeka with dreamhost, or have any insight in to what this could be?
