When you first setup your hosting account, there may be a need to access it immediately – before a domain is pointing to it or if DNS hasn’t yet resolved. All you need to do to in this instance is open up an FTP program and connect to your hosting account using your FTP credentials supplied in your welcome email.
Once connected navigate to and edit “public_html/wp-config.php”
Open up “wp-config.php” and add the following 2 lines of code directly above /* That’s all, stop editing! Happy blogging. */
define('WP_SITEURL', 'http://22.214.171.124/~account'); define('WP_HOME', 'http://126.96.36.199/~account');
Once your domain name has resolved to your hosting account, you can simply remove these 2 lines of code from “wp-config.php”.
