What do you mean by "tried to upload"? You clicked on the button
to upload... what do you do next, then what happens? When you say "it" said 'cant find part of the link' what is "it", your browser (pop-up window) or a response from the site? Please detail as much as possible. What is your OS and browser version? What kind of file are you trying to upload (gif, jpeg, etc.), what size (pixels), how big (kb), etc.?
