First, visit your site and refresh your browser.
If the changes you made in SiteStudio do not reflect on your site, it could be because your password for SiteStudio does not match the password for cPanel. Your cPanel password and username must stay the same from when you requested the SiteStudio account for it to continue to publish properly.
If you have updated your cPanel password you just need to notify us so we can update SiteStudio for you. Just email sales@hostgator.com with the updated information or you could submit the SiteStudio request again:

Note: Site Studio requires the domain name to be fully propagated and resolving to HostGator.
