Did you receive a 'Website Setup Confirmation' email when you signed up with Inet7? If so, you will find FTP login information in that email along with some brief tutorials on how to get started. You will need this information to enter it into an FTP client.
You can use an FTP client such as http://www.smartftp.com or https://filezilla-project.org/ (Download and install onto your local machine) and use your login credentials to upload website content to the web server:
FTP Host: IP address/hostname
Username: ftp username
Password: ftp password
Make sure that you transfer your website files to the /httpdocs directory which is your public directory (the files that are displayed on the Internet)
If you continue to have trouble, please e-mail [email protected] or call 651-293-0837x2 for assistance.
