Thanks for the response. I see all that, but it looks like I type in the hostname. It can be anything? Except localhost? For example "xxkjdnuefn" is okay?
Here is the photo. As you can see I still have "localhost" in there, because I am not sure what else to put in.
Also as usual it talks about propagating, so I am never sure if it is wrong, or just needs time.
oh, ok. i changed it from just "hostname" to "hostname.themodernist.com"
can log into wp-login.php
