I'm using attachment_fu for award nomination site and I'm running into a very strange problem that I've found absolutely zero information on. When running on our remote server (redhat fedora), I can only upload one file. After the classname/0000/0002 or whatever directory gets created once and the file is upload and written, I cannot seem to write to that directory ever again without deleting it. I don't get an error. I just get returned to the controller index with no uploaded data any time I try to write. The original file that was there remains intact and working until I destroy it (which works). Even after destroying it, I can't create a new file.
Interestingly enough, I don't have this problem at all when running on my local servers (two different macs). Only on the remote server.
Any help, suggestions, links, or just pointing in the right direction is most appreciated.
