This weekend I successfully moved my website from a stage area to the root of my domain, since it is ready to launch. I followed the steps on this page including Velvet Blues plugin:
When I tested the Jetpack Subscription, though, the confirmation email showed a link to the staged site, not the current URL.
Will it take a few days for the new URL to filter through to the Subscription widget? Is there anyway to change it in the code - if so, how and where?
