Attachments Problem

[dranged]

Hello, I'm currently having trouble with attachments. I uploaded the file to my FTP and then selected in the Attachments window "Upload File from an URL"
I'm putting in the correct URL but ever time I press Upload it says "invalid URL"
then I tried uploading it and it sent me from the little Attachments window to the home page.

What are the permissions set at for the directory you uploaded it to? You might try to modify the permissions for that directory but I am not sure if that will help or not.
