Hi there,
As I understand, on your dashboard, you see the site is connected using a different account, but you don’t know about the account. Correct?
You can first disconnect that account and connect yours. Please follow below steps:
1. Go to the Jetpack menu in your WP-Admin dashboard
2. Scroll down to find the Connections area.
3. Click Manage site connection.
4. Click Disconnect and follow the prompts to complete the disconnection process.
5. Click Set Up Jetpack button to connect your site to your WordPress.com account again.
This handy guide explains the full process in more detail: https://jetpack.com/support/reconnecting-reinstalling-jetpack/#disconnecting-jetpack
As a side note, you should not post the email address or any sensitive information in the forum as per guidelines.
Hi there,
It has been more than one week since we have heard from you, so I’m marking this topic as resolved. But If you have any further questions or need some more help, you’re welcome to reply here or open another thread.
