Thanks for your response. The problem is that it changes the name to a file called 'html', so if I upload for instance 'index.html' it changes the name to just 'html'. The file size is the same but the original file on the server remains unchanged and this new file appears! I'm sure it is saved as an HTML file, it's just not overwriting the original as it is supposed to. I can upload files with say FileZilla and it works fine but I wanted to use the software within the editor.
