Sometimes a temporary web site link contains an IP ADDRESS and looks like this:

http://174.136.3.119/~username

The issue is that the links in the web site won't work or the administrator panel (/administrator or /wp-login) won't work becase search-engine-friendly links are on.

This is resolved by using the SERVERNAME or FQDN rather than using the IP ADDRESS. Like this:

http://servername.directrouter.com/~username
