I've registered a domain name through Yola and want to get email addresses. I've registered with Google Apps as suggested, and it asks me to download a verification file and then upload it to my site. I don't how to do this. I've tried to upload a file through File Manager, and the file appears in the uploaded files but when try to confirm that it's there, I just get a message saying "404. Sorry, we can't seem to find that page, click here to return to the homepage".
