This site is an add on domain name. So do I have to type in the name of my main domain first? I have tried doing this, but all that happens is a 404 error. I contacted my web host, and was told that it means the folder or files have been deleted. I haven’t deleted anything from that site’s folder. From the view in the file manager, everything seems to be there.
Also, I have tried to manually upload the new version of wp to a new domain and get the same results. What could I be doing wrong?
