Hey again,
You should be able to see the log by following the information GoDaddy provide on that link I mentioned above.
If you're still unsure, I think you should chat with your host, they will be able to get them for you.
With regards to editing, renaming, etc, if you're not familiar with FTP then you can use the file manager that GoDaddy provide:

This way you should be able to follow Jan's instructions.
Take care.
