I'm not a newbie on this as I have 3 vshare servers with the bar working.... However.

This new site hosted on APT is not working.
When a user tries to upload a file the server tries to download the file called uu_upload.pl to the user's computer. I have checked persmissions and set them many times to 755. I have replaced the files using binary or course from original and from my other servers that are working. I have contacted help at APT and the answer is to replace the defective files.

I know that testing it by going to it directly should just show a grey screen with an error message if it is working. But when I do that it just downloads the file again.

Notes: If I turn off the progress bar uploads work as they should. Sorry, it is a private site so I cannot post the url but I would be happy to talk to admin. This is an addon domain under a main account. A second addon domain on the same server works fine! Huh?
