Everything is working fine with the downloads except that the zip file shows up with nothing in it.

I do have downloads by redirect turned on and what I have discovered is that there is nothing in the pub directory for those redirects. as the documentation says there should be. There is one folder named .ulcwvnoxjdtmrhrirl but it is empty.

This is a linux server, the folder permissions were set to 777 (and actually 755 should work as well). These zip files are very small.

This started happening after changing servers but don't know what to tell tech support - what server setting would create this problem?
