How To Configure Sync
After activating iThemes Sync, you’ll see the notice to Set Up Sync. Click on the Set Up Sync button and you're on your way.
Enter your iThemes username and password then click Sync.
Now you'll see the iThemes Sync page where you can either click the Go Manage Your Sites button or add additional users. Adding additional users is helpful if more than one person will be managing updates for this site.
