How do I update the site URL used by Jetpack subscribe widget [closed]

Contact the Jetpack support team and let us know your site URL. We’ll update your Jetpack settings for you.

Another alternative is to go to the Jetpack menu in your dashboard, and then click on “My jetpack” at the top of the page. You will then be able to disconnect your site from WordPress.com. Once you’ve done so, reconnect and you’ll be all set, and the reconnection will force an update of your Jetpack settings.

In the future, if you have more questions about Jetpack, I’d recommend contacting us directly or posting in the Jetpack support forums on WordPress.org. You have a better chance of getting a quick reply if you use the official support channels. 🙂
