(I have my AMP stack on a Solaris server.)
I'm getting the same error when uploading a file at Digital Library Manager.
This is the message I get when I try to upload the file.http://i.imgur.com/V2VKfVp.jpg
When I click on 'Save' again I get the following message, even though there's no duplicate file.http://i.imgur.com/DD6O8OC.jpg
After that if I visit File manager I can see a record for the file there. But this is just a record with file name, size and type. The actual file is not available. When I add the file to a new item under 'Digital Library Manager' and visit public view it's displayed as follows.http://i.imgur.com/a30qxqZ.jpg
When I download the file it won't open and would just give an error message saying the file is empty.
