Files not found when uploading

I've got 2 websites, one of which I've refreshed today and has been fine, the other just won't upload. I've moved to Smart thinking it was a problem with the other ftp software but I'm still not seeing the new data I've uploaded. I'm getting the following error messages:

Am I being thick here? I see mention of Size, but the file sizes are no larger than last month. I haven't changed the directory paths or anything like that. I've tried deleting the files off the remote server but they still appear on the web. I'm going round the twist here, can somebody please help

Hello ..

According to the log you posted the file is uploaded sucessfully to the server. Please make sure you are uploading the file to the right folder on the FTP server. If you delete a file on the server and it still appears on the web you may want to contact your web hosting provider for assistance.
