Hello.
m updating a website which has been created via Dreamweaver but am having problems uploading the files that I change. It used to be a case of Ctrl and s but it doesn't update but gives me the error message "An FTP error occurred - cannot put index.html.553 - can't open that file. Invalid argument". And nothing within the server will change after I renamed the files.

The file (index.html) does exist because the website is working (www.restorationonline.org.uk). I would really appreciate any assistance you could give me but please keep in mind I am new to Dreamweaver so I don't know much. Thank you for your time.
