Hi,
I did my web install and left the Host Directory blank. That may be an issue because the installer seemed to want a directory name in there. It structured the GET as www.pdmg.com/ /filename.00001 . It left a space in there and of course, it did not work.
I put in a subdirectory name and moved the files and then it was OK! It structured the GET as www.pdmg.com/pdmguser/filename.00001.
FWIW,
Ron Jolda
