Upload problems (error 550) Please help

Hi,

I'm having problems trying to upload some .htm files to ftp.

I have doubled checked with the server administrator that I have the right permissions to upload and other people (on different computers) have tried using the exact same ftp details, username and password - & have uploaded files with no problem. Below is the log of the error that I receive when I try to post / upload files.

I have also tried switching between active and passive modes (but still no joy uploading files)

Please could anyone help - Any help would be much appreciated.

Regards,

Jon
