Php File Management Upload Problem

Hello, This maybe a 5 minute job or a few hour job. I just switched my client site to my server and everything works fine except the upload portion of his file management program. When he goes to upload files through the file management program he gets this error "ERROR: Failed to find flength file" there is a link provided that takes us to this site <[login to view URL]> I believe this could be a settings issue for the new server or their could be more probelms. All of the files and ftp will be provided. I will need someone to be able to fix this issue very quickly. **** Watch this video ****** Here is a video of the problems: [[login to view URL]][1]
